    their radiation can be turned on and off. To generate X-rays, the electron accelerator needs to be equipped with an X-ray converter. The X-ray converter is designed to stop the accelerated electrons and is typically a water cooled tungsten or tantalum plate in an appropriate mechanical assembly. A lot
