Abstract

A normal-conducting S-band linear accelerator based 10 MeV photon FLASH radiotherapy X-ray source prototype was built. By using high-energy, high average current electron beam hitting a rotating target, a high dose rate of 80.5 Gy/s at a source-axis distance of 1 m was successfully obtained, which reaches the threshold for future clinical trial.
