    Electron beams generated by linear accelerators (LINACs) used in FLASH radiotherapy consist of microsecond pulses and are therefore characterized by instantaneous dose rates on the order of MGy/s. Diamond represents one ofthe most promising materials for fabricating reliable dosimeters for FLASH radiotherapy. So far, excellent results have been achieved using detectors based on high-quality single-crystal…

    S. Pettinato1,2; G. Felici3; L. Galluzzo3; M. Girolami2; M.C. Rossi4 and S. Salvatori1,2 Accurate dosimetry of ultra-high-dose-rate beams using diamond detectors remains challenging, primarily due to high photocurrent peaks that exceed the input dynamics of precision electrometers. This work aimed to demonstrate the effectiveness of compact gated integration electronics in conditioning current peaks (>20 mA) generated…
