Abstract :
Fringe effects of electric field distribution near the FEA surface in diode configuration are studied by mathematical modelling. Different anode shapes are considered: plane anode and spherical anode. Modelling results of surface electric field distribution are presented. The spherical shape of anode allows higher voltage (and higher field emission current) without destructive arcs risk.
