Operation of the Spallation Neutron Source (SNS) RF Systems provide a broad study of high-power equipment and sources including solid state amplifiers, tetrodes, klystrons, waveguide circulators and fundamental power couplers. While not unique to the SNS, over 20 years of operating at high average and peak powers have yielded insights to overcoming technical problems of interest to the wider...
Los Alamos Neutron Science Center started developing a replacement RF powerplant for the 100 MeV drift tube linac over twenty years ago, as there were lifetime issues with high duty factor (12% DF) operation using the RCA/Burle/Photonis 7835 power triode at 200 MHz. Cathode emission failures were predominantly happening at LANSCE at high average power, as 200 MHz injector linacs at BNL and...
SIRIUS is a 4th generation synchrotron light source built and operated by the Brazilian Synchrotron Light Laboratory (LNLS) currently operating in top-up mode at 100 mA beam current, driven by a temporary RF system comprised of one PETRA 7-cell cavity and two 65 kW solid state amplifiers (SSAs). In the upcoming update, two SRF cavities will be installed along with two more SSAs, which will...
The RF systems for the first phase for the European Spallation Source accelerator is nearing completion. A total of 91 high power systems will be installed to support an average power capability of a 2 MW beam on target. ESS is a long-pulse machine which will operate at 14 Hz, with 2.86 ms pulses. Commissioning to a low power dump is expected to start early 2025 ahead of commissioning to the...
