Electron and proton FLASH beam dosimetry using unified alanine, EBT‐XD, and HD‐V2 Gafchromic film dosimeters
The unified alanine and film dosimeters enabled simultaneous irradiation of the alanine and the films, with combined relative standard uncertainties of 2.4% (k = 1) for the alanine dosimeter and 3.5% (k = 1) for the EBT-XD films at the electron FLASH beam. For the proton FLASH beam, these uncertainties were 3.2% (k = 1) for both the alanine dosimeter and the EBT-XD films. Until dosimetry guidelines for the FLASH RT community are established by a working group such as AAPM TG-359, the dosimetry protocol proposed in this study can serve as a promising approach for FLASH RT facilities worldwide.
