Experimental demonstration of dark current mitigation by an over-inserted plug in a normal conducting very-high-frequency gun
The room temperature continuous wave (cw) very-high-frequency (VHF) gun is one of the candidates for the electron gun of the high-repetition-rate free-electron lasers (FELs). The VHF gun operates with a cathode gradient of ∼20 MV/m and an accelerating voltage of ∼750 kV. The gun dark current emiss...
