Abstract
A high-power transit-time oscillator producing 110kW at 5.7GHz in the TM010 cavity mode is described. The device comprises a temperature-lim ited diode electron gun operating at 40A in the range from 28kV to 35k V and an intermediate coaxial cavity from which the microwave power is extracted through a TEM coaxial guide. The diode serves also as a res onant cavity, where electromagnetic oscillations are grown from noise. The effect of the applied voltage on both the output microwave power and the instability saturation time has been investigated leading to a n optimal diode voltage of 33kV.
