Development of a high-power klystron for the Spallation Neutron Source

Summary form only given. The Spallation Neutron Source (SNS) will provide an intense beam of neutrons for scattering experiments. The SNS will be comprised of an ion source, a 1 GeV H/sup -/ linear accelerator, an accumulator ring, a target for neutron production, and an area for the scattering experiments. It is anticipated that anywhere from 36 high-power klystrons up to 160 lower-power klystrons operating at 805 MHz will be required, depending on the final design. In addition, 7-8 klystrons operating at 402.5 MHz will be required. Characteristics of the 805 MHz klystron are given.
