of radiation.
The primary beam is the most intense form of
radiation present at an accelerator facility and is
made inaccessible to personnel through
engineering design and administrative controls.
2.
Secondary beam
Secondary beam is produced by interaction of the
primary beam with targets or beamline
components. The secondary beam may consist
