Analysis of different protocols using an Exradin A12 cylindrical chamber for electron beam reference dosimetry

The Technical Report Series 398 (TRS-398), Electron Dosimetry Working Party (EWDP), and Task Group 51 (TG 51) are the most important protocols for reference dosimetry. In case of electron beam dosimetry, these recommend using parallel-plate ionization chambers beams with R50 values below specific thresholds. However, recent papers suggested cylindrical dosimetry all energies. Here we compared different a chamber recommendations TRS-398 formalism several We employed nominal energies 4, 6, 9, 12, 15 MeV Varian 2100C linear accelerator, an Exradin A12, P11 analysis. results showed differences 3% when comparing alternative These can bring confidence in which make procedure simpler faster.
