Design, Simulation and Compare of Flat Cathode Electron Guns with Spherical Cathode Electron Guns for Industrial Accelerators

Design and simulation of a 1 MeV, 100 mA parallel-fed capacitive coupled cascade industrial accelerator

“…Therefore, we can compare these guns to each other. Based on our application, the comparable parameters are as follows: the beam waist position, beam waist radius, Gaussianity of the profile, stability of performance after a long time and cost [14,15]. Figure 6 shows the schematic of the flat cathode Pierce electron gun.…”
