Self consistent theory for gyrotrons including effect of voltage depression

  • E. Borie
  • G. Gantenbein


The effect of the voltage depression due to space charge on the beam parameters in a gyrotron is investigated. Although the voltage depression can be compensated to some extent by increasing the beam voltage, some loss of efficiency is to be expected, especially in the case of high currents and volume modes.
