Abstract
A radiotherapy system includes an X-ray target configured to convert an incident electron beam into a therapeutic X-ray beam, a purging magnet configured to redirect unwanted particles emitted from the X-ray target away from the therapeutic X-ray beam, and a particle collector configured to absorb the unwanted particles subsequent to redirection by the purging magnet. The particle collector may be configured to dissipate at least 50% of the energy of the incident electron beam.
