  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.

  The Swiss spallation neutron source (SINQ) at Paul Scherrer Institut (PSI) provides beams of thermal and cold neutrons to different neutron instruments. In a view of a potential SINQ upgrade, an experimental program characterizing the current performance of SINQ neutron beams was started in 2013. We present experimental results of the irradiation of imaging plates and gold foils at one of SINQ thermal neutron beam lines that hosts the high resolution powder diffractometer (HRPT) and compare the experimental results to the numerical MCNPX simulations of the neutron flux from the SINQ target-moderator system.
