ENERGY FILTER FOR COLD FIELD EMISSION ELECTRON BEAM APPARATUS
摘要:
An electron beam apparatus and a method for providing an energy-filtered primary electron beam are described. Therein, a primary electron beam having an asymmetric first energy distribution is generated by means of an electron source. The primary electron beam is high-pass energy filtered using a retarding lens.
