Abstract :
This paper describes the simulation of an axi-symmetric 2-stage depressed collector including the effects of secondary electrons using a 2D FDM based code and compares its efficacy against experimental results and 3D simulation using CST Particle Studio. The paper also demonstrates the 3D simulation of a tilted electric field (TEF) collector using CST Studio for arresting the secondary electron back-migration.
