Proton dosimetry at the accelerator COSY for radiation effect testing

Radiochromic films are a useful tool for investigating the beam profile of particle beams for radiation effect testing. The films have to be calibrated for each type of radiation and its energy, for which we use ionization chambers. Additionally, we performed further experiments at various proton energies where we compare different dosimetry systems: an ESA SEU monitor, a calorimeter, and activation analysis. We achieve reproducibility for the calibrated energy range. Transferability to other proton energies than the calibration energy is not successful, instead calibration at the corresponding energy is suggested.
