The Spallation Neutron Source (SNS) accumulator ring is designed to accumulate, via H − injection, protons of 2 MW beam power at 1 GeV kinetic energy at a repetition rate of 60 Hz [1]. At such beam intensity, electron-cloud is expected to be one of the intensity-limiting mechanisms that complicate ring operations. This paper summarizes mitigation strategy(More)
Accelerators are the largest and most costly scientific instruments of the Department of Energy, with uses across a broad range of science, including colliders for particle physics and nuclear science and light sources and neutron sources for materials studies. COMPASS, the Community Petascale Project for Accelerator Science and Simulation, is a broad,(More)
The orotron (the Smith-Purcell electron microwave tube with open cavity) provides coherent radiation at the frequencies up to 0.4 THz. The output power of 50–100 mW is obtained in the microsecond pulses with possibility of a wide frequency tuning. A proposed new scheme of a frequency-multiplication regime allows increasing the orotron operating(More)
