Performance of the PSI High Power Accelerator M. Seidel and A.C. Mezger Paul Scherrer Institut, Villigen, Switzerland Corresponding Author: mike.seidel@psi.ch PSI operates a 590 MeV proton accelerator that drives a neutron spallation source and delivers
a high average beam power of up to 1.3 MW. In 2008 the Ring Cyclotron, which represents the
major component in the accelerator chain, was upgraded by installing the remaining two out of
four new and more powerful accelerating resonators.
This paper describes the performance of the facility achieved with these new resonators in terms of
beam power, grid-to-beam power transfer efficiency, beam losses and activation, statistics of beam
trips and run durations as well as overall reliability.
