Heavy Ion Fluence Measurements Based on Radiation Effects Generated in CTA Foils


The usefulness of cellulose triacetate (CTA) foils to measure heavy ion beam fluence was investigated. Two different CTA foils: FTR-125 Fuji dosimetric foil and Polish CTA-T technical foil, were examined. Ion beam irradiation (Ar, 155 MeV and Xe, 245 MeV) were performed on a 4-metre U-400 cyclotron operated in JINR, Dubna, Russia, and optical analysis — on a UV/VIS spectrophotometer Cintra-40 in INCT, Poland. Some results of gamma ray irradiation of CTA foils are included for comparison.

It was established that an increase of optical absorbance at 280 nm was strictly proportional to the fluences of the investigated ions for both kinds of foils. No postirradiation effects were observed. The results show that cellulose triacetate foils can be used for quick and easy measurement of ion beam fluences between 109 and 1011 ions/cm2 and also for evaluation of mean absorbed dose.
