Notes

Klystrons

Klystrons provide power to accelerate charged particles. They

emit X-rays during operation.

Radiofrequency cavities

These devices accelerate charged particles using

electromagnetic fields. Electrical discharges within the RF

cavity cause photon (ionizing radiation) emission.

Electrostatic separators/Septa

These devices split a particle beam into two beams using static
