Description
In 2019, the annual number of cancer cases exceeded 19 million, resulting in 10 million deaths worldwide. Radiation therapy stands out as one of the most effective methods for cancer treatment. Electron beams in the 100-MeV range can reach even deep-seated tumors without the need for surgical intervention. Thanks to novel high-gradient acceleration technologies, clinical facilities for high-energy electron–based irradiation are actively under development. In this talk, we give an overview of the existing low-energy electron and Very-High-Energy Electron (VHEE) machines capable of reaching ultra-high dose rates, thus enabling exploration of the potential FLASH effect. Furthermore, we shine a light on the planned VHEE UHDR medical facilities coming on stage in the next decade. We conclude by emphasizing the unsolved challenges associated with the exploitation of the FLASH effect, with special emphasis on the temporal structure of the delivered irradiation.
