The main objective of magnetic control in this phase is to first obtain sufficiently high electric field and connection length (implying a low poloidal magnetic field) in the breakdown region, and then, once plasma is formed, to force the plasma current to increase, guaranteeing force balance equilibrium. The problem is dominated by the presence of significant eddy currents induced in the passive structures and by the many constraints due to the coil system and power supplies. The present paper shows how, with minor simplifying hypotheses, the magnetic control design problem can be converted into a Quadratic Programming problem with both linear and quadratic constraints that can be solved with an ad hoc iterative algorithm. On the other hand, the full design problem, including the choice of possible Switching Network resistors, becomes nonlinear and an evolutionary Genetic Algorithm solver is proposed. The algorithms are tested on DEMO breakdown and early ramp-up design which is a quite challenging problem because of the large distance between active coils and vacuum chamber, the presence of shielding passive structures with large time constants, and the active constraints on the CS/PF coil system.}, year = {2022}, eissn = {1873-7196} } @article{MTMT:32831279, title = {Understanding the electromagnetic topology during the ohmic breakdown in tokamaks considering self-generated electric fields}, url = {https://m2.mtmt.hu/api/publication/32831279}, author = {Yoo, MG and Na, YS}, doi = {10.1088/1361-6587/ac5bb6}, journal-iso = {PLASMA PHYS CONTR F}, journal = {PLASMA PHYSICS AND CONTROLLED FUSION}, volume = {64}, unique-id = {32831279}, issn = {0741-3335}, abstract = {The physical mechanisms of the ohmic breakdown in a tokamak have been understood based on the classical Townsend avalanche theory.

It shows that size matters and that breakdown and plasma initiation differ in larger devices. The large thick and conductive ITER vessel slows down the prefill process, the development of the toroidal electric field and affects the dynamics of the poloidal magnetic field at breakdown. The large vacuum vessel requires more than 1 s for the prefill gas to spread over the vessel. It slows down the development of the toroidal electric field, applied to ionize the prefill gas, by about 1 s and complicates the control of the magnetic configuration required for plasma initiation. It is shown that the avalanche process that provides the initial ionization slows down towards the end, if the cross-section of the toroidal discharge is larger. On the other hand, a larger plasma volume is beneficial for the subsequent burn-through of main-species ionization and impurity line-radiation. ITER First Plasma operation aims to reach a minimum plasma current of 100 kA, which will require a full avalanche and a partial burn-through to reach electron temperatures of at least 10-20 eV. The burn-through limits the ITER prefill pressure upper range of about 1 mPa. These predictions are based on OD models of plasma initiation that furthermore assume the plasma volume remains constant. As burn-through is a critical process, models that consider radial profiles and/or volume dynamics, could provide further insight in the constraints of ITER plasma initiation. Electron cyclotron heating (ECH) high-power microwaves can be used to assist the ITER plasma initiation process. Although the ECH burn-through assist is reasonably well understood, no model exist that can predict the behaviour of ECH pre-ionization on ITER plasma initiation. ECH burn-through assist is shown to be ineffective for ITER First Plasma operations. Low prefill pressures are thought to increase the likelihood to develop a highly energetic supra-thermal electron discharge during the plasma initiation process. Considering supra-thermal electrons could affect the assumptions for the plasma resistance or even the ionization rate coefficient in plasma initiation models, hence altering the expected dynamics. Furthermore, only a qualitative picture of the processes that cause such supra-thermal discharges exists and a dedicated model is needed to improve ITER predictions.}, keywords = {ITER; plasma initiation; tokamak breakdown}, year = {2019}, eissn = {1741-4326} } @article{MTMT:31004868, title = {Analysis of Alfven eigenmode destabilization in ITER using a Landau closure model}, url = {https://m2.mtmt.hu/api/publication/31004868}, author = {Varela, J. and Spong, D.

The aim of the present study is to analyze the AE stability of different ITER operation scenarios considering multiple energetic particle species. We use the reduced magneto-hydrodynamic (MHD) equations to describe the linear evolution of the poloidal flux and the toroidal component of the vorticity in a full 3D system, coupled with equations of density and parallel velocity moments for the EP species including the effect of the acoustic modes. The AEs driven by the NBI EP and alpha particles are stable in the configurations analyzed, only MHD-like modes with large toroidal couplings are unstable, although both can be destabilized if the EP beta increases above a threshold. The threshold is two times the model beta value for the NBI EP and alpha particles in the reverse shear (RS) case, leading to the destabilization of Beta induced AE (BAE) near the magnetic axis with a frequency of 25-35 kHz and toroidal or elliptical AE (TAE/EAE) in the RS region with a frequency of 125-175 kHz, respectively. On the other hand, the hybrid and steady state configurations show a threshold 3 times larger with respect to the model beta for the alpha particle and 40 times for the NBI EP, also destabilizing BAE and TAE between the inner and middle plasma region. In addition, a extended analysis of the RS scenario where the beta of both alpha particles and NBI EP are above the AE threshold, multiple EP damping effects are also identified as well as optimization trends regarding the resonance properties of the alpha particle and NBI EP with the bulk plasma.}, keywords = {alpha particles; MHD; ITER; AE; EP}, year = {2019}, eissn = {1741-4326} } @article{MTMT:33721568, title = {Multi-machine analysis of termination scenarios with comparison to simulations of controlled shutdown of ITER discharges}, url = {https://m2.mtmt.hu/api/publication/33721568}, author = {de, Vries P.

The aim of this joint analysis is to compare the assumptions for ITER terminations with the present experience basis. The study examined the parameter ranges in which present day devices operated during their terminations, as well as the dynamics of these parameters. The analysis of a database, built using a selected set of experimental termination cases, showed that, the H-mode density decays slower than the plasma current ramp-down. The consequential increase in f(GW) limits the duration of the H-mode phase or result in disruptions. The lower temperatures after the drop out of H-mode will allow the plasma internal inductance to increase. But vertical stability control remains manageable in ITER at high internal inductance when accompanied by a strong elongation reduction. This will result in ITER terminations remaining longer at low q (q(95) similar to 3) than most present-day devices during the current ramp-down. A fast power ramp-down leads to a larger change in beta(P) at the H-L transition, but the experimental data showed that these are manageable for the ITER radial position control. The analysis of JET data shows that radiation and impurity levels significantly alter the H-L transition dynamics. Self-consistent calculations of the impurity content and resulting radiation should be taken into account when modelling ITFR termination scenarios. The results from this analysis can be used to better prescribe the inputs for the detailed modelling and preparation of ITER termination scenarios.}, keywords = {plasma control; tokamak operation; termination scenario}, year = {2018}, eissn = {1741-4326}, orcid-numbers = {Vicente, J./0000-0002-3883-1796} } @article{MTMT:30511343, title = {On the breakdown modes and parameter space of ohmic tokamak start-up}, url = {https://m2.mtmt.hu/api/publication/30511343}, author = {Peng, Yanli and Jiang, Wei and Innocenti, Maria Elena and Zhang, Ya and Hu, Xiwei and Zhuang, Ge and Lapenta, Giovanni}, doi = {10.1017/S0022377818001046}, journal-iso = {J PLASMA PHYS}, journal = {JOURNAL OF PLASMA PHYSICS}, volume = {84}, unique-id = {30511343}, issn = {0022-3778}, abstract = {Tokamak start-up is strongly dependent on the state of the initial plasma formed during plasma breakdown. We have investigated through numerical simulations the effects that the pre-filling pressure and induced electric field have on pure ohmic heating during the breakdown process. Three breakdown modes during the discharge are found, as a function of different initial parameters: no breakdown mode, successful breakdown mode and runaway mode. No breakdown mode often occurs with low electric field or high pre-filling pressure, while runaway electrons are usually easy to generate at high electric field or low pre-filling pressure (<1.33 x 10(-4) Pa). The plasma behaviours and the physical mechanisms under the three breakdown modes are discussed. We have identified the electric field and pressure values at which the different modes occur. In particular, when the electric field is 0.3 V m(-1) (the value at which ITER operates), the pressure range for possible breakdown becomes narrow, which is consistent with Lloyd's theoretical prediction. In addition, for 0.3 V m(-1), the optimal pre-filling pressure range obtained from our simulations is 1.33 x 10(-3) similar to 2.66 x 10(-3) Pa, in good agreement with ITER's design. Besides, we also find that the Townsend discharge model does not appropriately describe the plasma behaviour during tokamak breakdown due to the presence of a toroidal field. Furthermore, we suggest three possible operation mechanisms for general start-up scenarios which could better control the breakdown phase.}, keywords = {plasma simulation; fusion plasma}, year = {2018}, eissn = {1469-7807} } @article{MTMT:30404803, title = {Assessment of the baseline scenario at q(95) similar to 3 for ITER}, url = {https://m2.mtmt.hu/api/publication/30404803}, author = {Sips, A.

The m = 2/n = 1 tearing modes, occurring after several pressure-relaxation times, are linked to the shape of the current profile in the outer region of the plasma. The q = 2 surface is located at rho similar to 0.78, near a minimum in J. A steeper 'well' around the q = 2 surface is correlated with the instabilities, and this finding is consistent for modes that occur both early (<1 tau R) and late (>2 tau R) on the beta(N) flattop, at high and low input torque, for discharges with and without direct electron heating. Low rotation or differential rotation in the core plasmas is shown to not be the direct cause of the onset of these instabilities. The current profile trends identified in this work indicate that the modes limiting the Q = 10 operation in the ITER demonstration plasmas are likely due to the slow evolution of the current profile,

with a programmatic focus on the qualification of ITER operating scenarios, the consolidation of ITER design choices and preparation for plasma operation with the ITER-like wall presently being installed in JET. Good progress has been achieved, including stationary ELMy H-mode operation at 4.5 MA. The high confinement hybrid scenario has been extended to high triangularity, lower rho* and to pulse lengths comparable to the resistive time. The steady-state scenario has also been extended to lower rho* and nu* and optimized to simultaneously achieve, under stationary conditions, ITER-like values of all other relevant normalized parameters. A dedicated helium campaign has allowed key aspects of plasma control and H-mode operation for the ITER non-activated phase to be evaluated. Effective sawtooth control by fast ions has been demonstrated with (3)He minority ICRH, a scenario with negligible minority current drive. Edge localized mode (ELM) control studies using external n = 1 and n = 2 perturbation fields have found a resonance effect in ELM frequency for specific q(95) values. Complete ELM suppression has, however, not been observed, even with an edge Chirikov parameter larger than 1. Pellet ELM pacing has been demonstrated and the minimum pellet size needed to trigger an ELM has been estimated. For both natural and mitigated ELMs a broadening of the divertor ELM-wetted area with increasing ELM size has been found. In disruption studies with massive gas injection up to 50% of the thermal energy could be radiated before, and 20% during, the thermal quench. Halo currents could be reduced by 60% and, using argon/deuterium and neon/deuterium gas mixtures, runaway electron generation could be avoided. Most objectives of the ITER-like ICRH antenna have been demonstrated; matching with closely packed straps, ELM resilience, scattering matrix arc detection and operation at high power density (6.2 MW m(-2)) and antenna strap voltages (42 kV). Coupling measurements are in very good agreement with TOPICA modelling.}, year = {2011}, eissn = {1741-4326} } @article{MTMT:1847517, title = {The role of JET for the preparation of the ITER exploitation}, url = {https://m2.mtmt.hu/api/publication/1847517}, author = {Romanelli, F and Laxaback, M and Durodie, F and Horton, L and Lehnen, M and Murari, A and Rimini, F and Sips, G and Zastrow, KD}, doi = {10.1016/j.fusengdes.2011.02.059}, journal-iso = {FUSION ENG DES}, journal = {FUSION ENGINEERING AND DESIGN}, volume = {86}, unique-id = {1847517}, issn = {0920-3796}, abstract = {The JET programme is devoted to the consolidation of ITER design choices and the qualification of ITER integrated regimes of operation. During the experimental campaigns carried out in 2008 and 2009 attention focussed on the test of the ITER-like ICRH antenna, the ITER scenario preparation, the verification of the adequacy of the ITER poloidal field coil design and the test of disruption mitigation methods such as massive gas injection. From 2011 the new ITER-like wall with all beryllium and tungsten plasma facing components, the neutral beam power upgrade and the enhanced control and diagnostic capability will allow key questions on plasma-wall interactions, fuel retention and plasma impurity control with the foreseen ITER wall materials to be addressed. Finally, feasibility studies have confirmed the option of installing an ITER-technology based 170 GHz/10 MW electron cyclotron resonance heating system for the control of MHD activity and the development of advanced tokamak scenarios, and 32 in-vessel coils for ELM control capable of producing magnetic perturbation spectra with a Chirikov parameter above unity for plasma currents up to 5 MA. During the ITER construction phase, JET will be the only device of its class in operation and will therefore play a key role in the preparation of ITER operations - saving time and reducing risk from the ITER programme.

current ramp-up phase of ITER demonstration discharges, performed at JET, is analysed and the capability of the empirical L-mode Bohm-gyroBohm and Coppi-Tang transport models as well as the theory-based GLF23 model to predict the temperature evolution in these discharges is examined. The analysed database includes ohmic (OH) plasmas with various current ramp rates and plasma densities and the L-mode plasmas with the ion cyclotron radio frequency (ICRF) and neutral beam injection (NB!) heating performed at various ICRF resonance positions and NBI heating powers. The emphasis of this analysis is a data consistency test, which is particularly important here because some parameters, useful for the transport model validation, are not measured in OH and ICRF heated plasmas (e.g. ion temperature, effective charge). The sensitivity of the predictive accuracy of the transport models to the unmeasured data is estimated. It is found that the Bohm-gyroBohm model satisfactorily predicts the temperature evolution in discharges with central heating (the rms deviation between the simulated and measured temperature is within 15%), but underestimates the thermal electron transport in the OH and off-axis ICRF heated discharges. The Coppi-Tang model strongly underestimates the thermal transport in all discharges considered. A re-normalization of these empirical models for improving their predictive capability is proposed. The GLF23 model, strongly dependent on the ion temperature gradient and tested only for NBI heated discharges with measured ion temperatures, predicts accurately the temperature in the low power NBI heated discharge (rms < 10%) while the discrepancy with the data increases at high power. Based on the analysis of the JET discharges, the modelling of the current ramp-up phase for the H-mode ITER scenario is performed with particular emphasis on the sensitivity of the sawtooth-free duration of this phase to transport model.}, year = {2010}, eissn = {1361-6587} } @article{MTMT:2509395, title = {Compatibility of ITER scenarios with full tungsten wall in ASDEX Upgrade}, url =

for ITER and on physics issues essential for the consolidation of design choices and the efficient exploitation of ITER. Particular attention has been given to the characterization of the edge plasma, pedestal energy and edge localized modes (ELMs), and their impact on plasma facing components (PFCs). Various ELM mitigation techniques have been assessed for all ITER operating scenarios using active methods such as resonant magnetic field perturbation, rapid variation of the radial field and pellet pacing. In particular, the amplitude and frequency of type I ELMs have been actively controlled over a wide parameter range (q(95) = 3-4.8, beta(N) <= 3.0) by adjusting the amplitude of the n = 1 external perturbation field induced by error field correction coils. The study of disruption induced heat loads on PFCs has taken advantage of a new wide-angle viewing infrared system and a fast bolometer to provide a detailed account of time, localization and form of the energy deposition. Specific ITER-relevant studies have used the unique JET capability of varying the toroidal field (TF) ripple from its normal low value delta(BT) = 0.08% up to delta(BT) = 1% to study the effect of TF ripple on high confinement-mode plasmas. The results suggest that delta(BT) < 0.5% is required on ITER to maintain adequate confinement to allow Q(DT) = 10 at full field. Physics issues of direct relevance to ITER include heat and toroidal momentum transport, with experiments using power modulation to decouple power input and torque to achieve first experimental evidence of inward momentum pinch in JET and determine the threshold for ion temperature gradient driven modes. Within the longer term JET programme in support of ITER, activities aiming at the modification of the JET first wall and divertor and the upgrade of the neutral beam and plasma control systems are being conducted. The procurement of all components will be completed by 2009 with the shutdown for the installation of the beryllium wall and tungsten divertor extending from summer 2009 to summer 2010.}, year = {2009}, eissn = {1741-4326} } @article{MTMT:25611053, title = {22nd IAEA Fusion Energy Conference: summary of contributions on Fusion Technology and ITER Activities}, url = {https://m2.mtmt.hu/api/publication/25611053}, author = {Stork, D}, doi = {10.1088/0029-5515/49/10/104002}, journal-iso = {NUCL FUSION}, journal = {NUCLEAR FUSION}, volume = {49}, unique-id = {25611053}, issn = {0029-5515}, year = {2009}, eissn = {1741-4326} } @article{MTMT:2933104, title = {Lower hybrid heating and current drive on the Alcator C-Mod tokamak}, url = {https://m2.mtmt.hu/api/publication/2933104}, author = {Wilson, JR and Parker, R and Bitter, M and Bonoli, PT and Fiore, C and Harvey, RW and Hill, K and Hubbard, AE and Hughes, JW and Ince-Cushman, A and Kessel, C and Ko, JS and Meneghini, O and Phillips, CK and Porkoláb, Miklós and Rice, J and Schmidt, AE and Scott, S and Shiraiwa, S and Valeo, E and Wallace, G and Wright, JC}, doi = {10.1088/0029-5515/49/11/115015}, journal-iso = {NUCL FUSION}, journal = {NUCLEAR FUSION}, volume = {49}, unique-id = {2933104}, issn = {0029-5515}, year = {2009}, eissn = {1741-4326} } @article{MTMT:1312918, title = {Overview of ASDEX Upgrade results}, url = {https://m2.mtmt.hu/api/publication/1312918}, author = {Zohm, H and Adamek, J and Angioni, C and Antar, G and Atanasiu, CV and Balden, M and Becker, W and Behler, K and Behringer, K and Bergmann, A and Bertoncelli, T and Bilato, R and Bobkov, V and Boom, J and Bottino, A and Brambilla, M and Braun, F and Brudgam, M and Buhler, A and Chankin, A and Classen, I and Conway, GD and Coster, DP and de Marne, P and D, Inca R and Drube, R and Dux, R and Eich, T and Engelhardt, K and Esposito, B and Fahrbach, HU and Fattorini, L and Fink, J and Fischer, R and Flaws, A and Foley, M and Forest, C and Fuchs, JC and Gál-Hobirk, Kinga Izabella and Munoz, MG and Adamov, MG and Giannone, L and Gorler, T and Gori, S and da Graca, S and Granucci, G and Greuner, H and Gruber, O and Gude, A and Gunter, S and Haas, G and Hahn, D and Harhausen, J and Hauff, T and Heinemann, B and Herrmann, A and Hicks, N and Hobirk, J and Holzl, M and Holtum, D and Hopf, C and Horton, L and Huart, M and Igochine, V and Janzer, M and Jenko, F and Kallenbach, A and Kálvin, Sándor Csaba and Kardaun, O and Kaufmann, M and Kick, M and Kirk, A and Klingshirn, HJ and Koscis, G and Kollotzek, H and Konz, C and Krieger, K and Kurki-Suonio, T and Kurzan, B and Lackner, K and Lang, PT and Langer, B and Lauber, P and Laux, M and Leuterer, F and Likonen, J and Liu, L and Lohs, A and Lunt, T and Lyssoivan, A and Maggi, CF and Manini, A and Mank, K and Manso, ME and Mantsinen, M and Maraschek, M and Martin, P and Mayer, M and McCarthy, P and McCormick, K and Meister, H and Meo, F and Merkel, P and Merkel, R and Mertens, V and Merz, F and Meyer, H and Mlynek, A and Monaco, F and Muller, HW and Munich, M and Murmann, H and Neu, G and Neu, R and Neuhauser, J and Nold, B and Noterdaeme, JM and Pautasso, G and Pereverzev, G and Poli, E and Potzel, S and Puschel, M and Putterich, T and Pugno, R and Raupp, G and Reich, M and Reiter, B and Ribeiro, T and Riedl, R and Rohde, V and Roth, J and Rott, M and Ryter, F and Sandmann, W and Santos, J and Sassenberg, K and Sauter, P and Scarabosio, A and Schall, G and Schilling, HB and Schirmer, J and Schmid, A and Schmid, K and Schneider, W and Schramm, G and Schrittwieser, R and Schustereder, W and Schweinzer, J and Schweizer, S and Scott, B and Seidel, U and Sempf, M and Serra, F and Sertoli, M and Siccinio, M and Sigalov, A and Silva, A and Sips, CC and Speth, E and Stabler, A and Stadler, R and Steuer, KH and Stober, J and Streibl, B and Strumberger, E and Suttrop, W and Tardini, G and Tichmann, C and Treutterer, W and Troster, C and Urso, L and Vainonen-Ahlgren, E and Varela, P and Vermare, L and Volpe, F and Wagner, D and Wigger, C and Wischmeier, M and Wolfrum, E and Wursching, E and Yadikin, D and Yu, Q and Zasche, D and Zehetbauer, T and Zilker, M}, doi = {10.1088/0029-5515/49/10/104009}, journal-iso = {NUCL FUSION}, journal = {NUCLEAR FUSION}, volume = {49}, unique-id = {1312918}, issn = {0029-5515}, abstract = {ASDEX Upgrade was operated with a fully W-covered wall in 2007 and 2008. Stationary H-modes at the ITER target values and improved H-modes with H up to 1.2 were run without any boronization. The boundary conditions set by the full W wall (high enough ELM frequency, high enough central heating and low enough power density arriving at the target plates) require significant scenario development, but will apply to ITER as well. D retention has been reduced and stationary operation with saturated wall conditions has been found. Concerning confinement, impurity ion transport across the pedestal is neoclassical, explaining the strong inward pinch of high-Z impurities in between ELMs. In improved H-mode, the width of the temperature pedestal increases with heating power, consistent with a beta(1/2)(pol,ped) scaling. In the area of MHD instabilities, disruption mitigation experiments using massive Ne injection reach volume averaged values of the total electron density close to those required for runaway suppression in ITER. ECRH at the q = 2 surface was successfully applied to delay density limit disruptions. The characterization of fast particle losses due to MHD has shown the importance of different loss mechanisms for NTMs, TAEs and also beta-induced Alfven eigenmodes (BAEs). Specific studies addressing the first ITER operational phase show that O1 ECRH at the HFS assists reliable low-voltage breakdown. During ramp-up, additional heating can be used to vary l(i) to fit within the ITER range. Confinement and power threshold in He are more favourable than in H, suggesting that He operation could allow us to assess H-mode operation in the non-nuclear phase of ITER operation.}, year = {2009}, eissn = {1741-4326} }
