Abstract :
To evaluate the computational time performance of three computational tools: EGUN2, XMGUN and CST, a 0.47μPerv, 1kV axis-symmetric gridless electron gun, working under the space charge-limited flow, was analyzed. It was observed, between the three codes, a good electric current agreement but the 2.5D codes presented better time responsive.
