Low Threshold-Energy Ionization Chamber System for Monitoring in Proton Therapy

Low Threshold-Energy Ionization Chamber System for Monitoring in Proton Therapy

A system of two low threshold-energy air ionization chambers 3 mg cm −2 thick is created. The system includes a new two-gap chamber that has a sensitive area of 113 cm 2 , 1 mm gaps between electrodes made of polyimide films 3 µm thick, and a multichannel chamber. The contribution to the dose from r...

Zusammenfassung:A system of two low threshold-energy air ionization chambers 3 mg cm −2 thick is created. The system includes a new two-gap chamber that has a sensitive area of 113 cm 2 , 1 mm gaps between electrodes made of polyimide films 3 µm thick, and a multichannel chamber. The contribution to the dose from recombination, low-energy protons, and δ-electrons is investigated. The total radiation dose of the system is 5 Mrad.
