Evaluation of the Exradin A30 Parallel Plate Ion Chamber As a Reference Dosimeter In Ultra-High Dose Rate (UHDR) Electron Beam
Ultra-high dose rate (UHDR) beams (40Gy/s) compromise the accuracy of conventional reference ion chambers (ICs) due to saturation effects. The Exradin A30 is an ultra-thin parallel-plate IC featuring a 0.3 mm nominal electrode spacing to enhance the charge co...

Performance Evaluation of the New Commercial Exradin A30 Ion Chamber for Uhdr Reference Dosimetry
Ionization chambers represent the gold standard for clinical dosimetry; however, they suffer from severe ion recombination losses at the ultra-high dose rates (UHDR) characteristic of FLASH radiotherapy. This study evaluates the new commercial Exradin A30 par...
