Abstract

Describes a 805 MHz, 2.75 MW peak power klystron in support of the Spallation Neutron Source currently under construction in Oak Ridge, Tennessee. The klystron was tested at a pulse length of 1.67 msec and a repetition rate of 60 Hz (10% duty) producing an average power of 275 kW. The electron beam was produced by an anode controlled electron gun operating with a nominal cathode voltage of 107 kV and a current of 43 A. The amplifier section consisted of a total of 6 cavities, including one cavity operating at the second harmonic. Each of the cavities, with the exception of the output cavity, incorporated tuners, allowing their resonant frequencies to be optimized.
