Glossary of Terms

Beamline physicist - A physicist responsible for creating a beamline design to meet the desired beam parameters such as particle type, intensity, and backgrounds. The beamline physicist specifies all beamline components such as magnets, collimators, instrumentation.

Safety Warden - A individual assigned to each building who is responsible for ensuring a safe working environment within the building.

Conduct of Operations (COO) - A Department Of Energy Order (DOE 5480.19) that specifies requirements for operating a facility to ensure the safety of on-site personnel and the general public. (See Appendix )

EPICS - The beamline / slow controls system used in the CEBAF Physics and Accelerator Divisions.

Hazard Assessment - A description of hazards and potential consequences when no credit is taken for active controls on the hazards.

Liaison Physicist - A physicist familiar with an experiment who is the primary co ntact person with Physics division. Represents the experiment at Physics division planning meetings.

LOTO - Lockout Tagout

MSDS - Material Safety Data Sheet. Required document for all chemicals used. Describes toxic, hazardous and flammability aspects of the chemical.

ODH - Oxygen deficiency hazard. Term used to describe a condition where the oxygen level may fall below 19%, due to oxygen-displacing gases.

Radiation Control Officer - An individual who acts on behalf of a division head in all aspects of radiation safety.

Running condition - A document that specifies the mode of beamline operation and imposes limits on beam intensity, magnet current interlocks and currents, radiation monitor interlocks, and gate/fence configuration.

Safety Assessment Document (SAD) - A document that describes how all the hazards in the experiment are controlled. (See Chapter ).
