title = "Effect of trapped electrons on gyrotron efficiency",
abstract = "The effect of electron trapping in the presence of a depressed collector has been included in gyrotron efficiency computations. A condition for trapping is derived in terms of the retarding voltage. Electron reflection is treated both as an ideal adiabatic process and a non-adiabatic one to find limits for realistic cases. The overall electron efficiency as a function of the retarding voltage has been calculated for two specific gyrotrons with allowance for the electron velocity spread. The collector voltages corresponding to the onset of trapping are specified and the resulting efficiency decrease is found.",
