   Physical and mathematical model is developed for the numerical simulation of electron transport in multi-electrodes microcell with circular emitter. Electron beam transport in self-consistent electric field is simulated using cylindrical particle mesh code. Some typical examples are presented for demonstrating the effectiveness of the proposed technique for optimization of the beam control. The influence of a magnetic field and a secondary emission of electros on the static and dynamic characteristics of a microcell iss studied. The microvacuum cell is shown to be used as a magnetosensitive element.
