The Dosimetry of Proton Beams in Flash-Therapy

Methods of dosimetry of proton beams with a high dose rate are investigated in this work. Standard ionization chambers proved to be inapplicable at dose rates above 100 Gy s –1 , and the measurements of radiochromic EBT-XD films need to be corrected for linear energy transfer. The developed Cherenko...

Summary:Methods of dosimetry of proton beams with a high dose rate are investigated in this work. Standard ionization chambers proved to be inapplicable at dose rates above 100 Gy s –1 , and the measurements of radiochromic EBT-XD films need to be corrected for linear energy transfer. The developed Cherenkov monitor showed good agreement between measurements of the intensity of proton pulses.
