  The issue of activation of a Tungsten collimator by protons is considered for the incident energy of 12.2 MeV. Two different simulation approaches using the Monte Carlo programs MCNPX and FLUKA are applied to estimate the equivalent remanent dose rate after the irradiation of the collimator. The results of the numerical simulation are then compared to the measured dose levels of the collimator of the COMET cyclotron at Paul Scherrer Institut (PSI).

  The proton channel of the PSI high intensity proton accelerator (HIPA) transports the beam from the extraction point of the ring cyclotron through two meson production graphite targets up to the SINQ spallation source. After many years of continuous improvement, the HIPA accelerator complex has now reached the remarkable beam power of 1.4 MW. The next power upgrade is foreseen for the near future. In order to achieve this further step, an optimization of the beam optics in the proton channel is required with the goal of keeping the beam losses at a reasonable extent and, at the same time improve the beam distribution on the SINQ target.
