Numerical modelling of microvacuum magnetosensitive cell

Abstract

Cylindrical microvacuum cell with circular edge cathode and two coaxial plate face anodes is considered as a magnetosensitive element. Electron beam transport in self-consistent electric field is simulated using cylindrical particle-in-mesh code. Static and dynamic characteristics of magnetosensitive element are studied. Several circular grid electrodes are included in the model to control the electron beam. A target plate face electrode is considered as a secondary electron source.
