Using an electron gun and an angle measurement tool, we confirmed that a two-dimensional angular distribution could be measured at once over a large solid angle of +/- 45 degrees. We also confirmed that energy analysis could be performed with an aperture. Here a high energy resolution of similar to 0.23% was obtained by using the aperture size of 0.8 mm. at the 40 degrees position. Moreover, a magnified image of SUS316 #100 mesh was successfully measured.

The forecast calculations are based on a simple and relatively easily implementable algorithm. The parallelization is provided on the mathematical layer which is the highest possible level of parallelizing an algorithm for the solution of a system of differential equations. Our future goal is to move to solely DSN-PC measurement-based computations to make weather forecasts, but we do not have sufficient number of stations installed yet. However, a hybrid solution where we included NOAA Global Forecast System (GFS) data in the production of the initial values made it possible to test our sensor network’s capability of performing such calculations. To evaluate the viability of our approach we analyzed the error of the forecasts. Below the results of the distributed calculations are shown along with the method of the assimilation of the two datasets.}, year = {2019}, pages = {510-523}, orcid-numbers = {Tóth, László/0000-0003-3560-1044} } @article{MTMT:30564280, title = {Variable-deceleration-ratio wide-acceptance-angle electrostatic lens for two-dimensional angular and energy analysis}, url = {https://m2.mtmt.hu/api/publication/30564280}, author = {Matsuda, Hiroyuki and Tóth, László and Daimon, Hiroshi}, doi = {10.1063/1.5043317}, journal-iso = {REV SCI INSTRUM}, journal = {REVIEW OF SCIENTIFIC INSTRUMENTS}, volume = {89}, unique-id = {30564280}, issn = {0034-6748}, abstract = {Variable-deceleration-ratio wide-acceptance-angle electrostatic lens (VD-WAAEL) is proposed as a potential technique for two-dimensional angular and energy analysis. The basic features of the lens are studied using the charge simulation method and ray tracing calculation. The lens uses an ellipsoidal mesh electrode and allows a wide acceptance angle of +/- 50 degrees. Two possible applications of the VD-WAAEL are discussed. One is a simple combination of the VD-WAAEL-projection-lens, in which an aperture is used for energy analysis. The other is a combination of the VD-WAAEL with a conventional electron spectrometer, which is responsible for obtaining higher energy resolution. The former is discussed in detail and the latter is described briefly. While the ray tracing calculation is only for the case of an ideal mesh, a note on the disturbing effect of mesh holes is presented. The best possible energy resolution of the simple VD-WAAEL-projection-lens analyzer seems to be around 1/1000, given a fine mesh electrode to suppress the disturbing effect of mesh holes.
