Abstract

A triode-type cusp electron gun was optimized through numerical simulations for a W-band gyrotron traveling wave amplifier. An additional electrode in front of the cathode could switch the electron beam on and off instantly when its electric potential is properly biased. An optimal electron beam of current 1.7 A and velocity ratio (alpha) of 1.12 with an alpha spread of ~10.7% was achieved when the triode gun was operated at 40 kV.
