The paper elucidates some new computer modeling and experimental results on the design of a photoelectron gun with time-dependent electric field. The main essence of the new approach is based on the fact that the properly chosen electric field ramp e

Publisher Summary The problems of charged particle optics often require the electric charge of the bunch to be taken into account. In some cases—for instance, in electron guns and ion traps—the space charge effects dominate in electron bunch form
