[en] The measurement systems consisting of a Faraday cup, a total-absorption calorimeter and film dosimeters have been developed for dosimetry for heavy charged particle (ion) beams with kinetic energy per nucleon of about 5-20 MeV/amu which are provided by the TIARA AVF cyclotron. The uncertainty in the fluence measurement using a Faraday cup was estimated to be ±2%(1σ) by comparison of the measured values and the calculated values based on the energy fluence obtained using a total-absorption calorimeter and the nominal incident particle energy derived from the accelerator parameters. Several film dosimeters, well-characterized for low LET radiations, were irradiated by ion beams on the basis of this real-time beam monitoring and their dose responses were compared with those for low LET radiations. The results show that the dose response has a tendency to decrease with LET for radiochromic dye film FWT-60 and alanine film dosimeters. Combining uncertainty components for fluence measurement (±2%) and film dosimetry (±4%), the overall uncertainty in ion beam dosimetry is better than ±5%(1σ), which meets the requirements of material science and biological research.
