Abstract (English)	FLASH radiotherapy performed with ultra high dose rates (UHDR) or ultra high dose per pulse (UHDPP) beams has the potential to significantly reduce the side effects experienced by cancer patients, and to improve their quality of life. At present, new UHDPP electron and UHDR proton beam facilities are being installed or being upgraded to prepare for clinical FLASH radiotherapy. However, future widespread clinical introduction of FLASH radiotherapy requires reliable methods for traceable dosimetry under reference conditions (reference dosimetry). Further to this, development of Codes of Practice (CoP) for reference dosimetry in FLASH radiotherapy facilities is hampered by the lack of suited primary standards, characterised secondary standards, and solid methodology. This project will address these issues by developing traceable dosimetry, including upgraded primary and characterised secondary standards, to support the development of reference dosimetry CoPs required by UHDPP electron and UHDR proton beam facilities.
