| Abstract |
The Bonn Isochronous Cyclotron provides proton, deuteron, alpha particle and other light ion beams, having a charge-to-mass ratio Q/A >= 1/2, with kinetic energies in the range of 7 to 14 MeV per nucleon. At the irradiation site, a 14 MeV proton beam with a diameter of a few mm is used to irradiate detectors, so-called devices under test (DUTs), housed in a thermally-insulated and gas-cooled box. To ensure homogeneous damage application, the DUT is moved through the beam in a row-wise scan pattern with constant velocity and a row separation, smaller than the beam diameter. During irradiation, beam parameters are continuously measured non-destructively using a calibrated, secondary electron emission-based beam monitor, installed at the exit to the site. This allows a beam-driven irradiation scheme, enabling the setup to autonomously react to changing beam conditions, resulting in highly-uniform proton fluence distributions with relative uncertainties of typically 2%. In this work, the accelerator facility is introduced, the proton irradiation site with focus on its beam diagnostics is presented in detail and resulting fluence distributions are shown.
