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

electric fields. The high voltages associated with these devices

cause electrons to accelerate in the vacuum within the

beamline. They emit X-rays. Septa are also a high source of

activation and residual radiation.

Facility-Specific

Location of facility-specific ancillary sources.

IV.

TYPES OF CONTROLS

Controls are used at accelerator facilities to protect personnel from

exposure to ionizing radiation and other hazards including:

Electrical.

Mechanical.

Cryogenic.

Non-ionizing radiation.

The design of an effective safety program incorporates a combination

of:

Engineered controls.

Administrative controls.

Personal protective equipment, e.g., respirators, protective

clothing, etc.
