Sapphire dosimetric sensors for carbon ion beam radiation therapy
This study presents the first experimental results on sapphire sensors tested with 175 and 380 MeV/nucleon carbon ion beams. The measurements include the sensor signal curves of dependence on applied voltage (50–500 V), the signal variations with carbon ion beam intensity, and the correlation between absorbed dose in EBT‑3 radiochromic film (positioned in front of the sensors) and total charge registered by the sensors. Additionally, signal stability is assessed at 500 V under constant beam intensity following the irradiation dose monitoring by a relative dosimeter. For the first time, the differential absorbed dose distribution in a water phantom (Bragg curve) is measured using sapphire sensors. The detector signals are recorded at 500 V with a 900 ms integration time across the beam intensities ranging from 7.0·107 to 4.5·108 ions/pulse.
