VHEE radiotherapy fires electrons at 100 to 250 MeV, energies that reach deep tumours and can be steered by magnets, aiming to deliver FLASH-speed radiation from a machine smaller and cheaper than a proton facility. It is still at the accelerator-development and preclinical stage: no patient had been treated by September 2026.
Electrons in the 100-250 MeV range penetrate deeply, are steerable by magnets, and can be delivered at the ultra-high dose rates associated with the FLASH effect, in principle for a fraction of the cost of a proton facility. Work is at the accelerator-development and preclinical stage at CHUV/CERN, SLAC and elsewhere; the FLASH studies that exist in humans use conventional-energy electrons for skin lesions (for example NCT06549439, completed) or protons. No VHEE patient treatment had been reported by September 2026.
Very-high-energy electrons deposit a relatively flat depth dose that can be shaped magnetically, enabling deep targets and millisecond delivery.
