Search and Evict

Before beam can be sent into an area that has been previously open to workers, operators must secure this area and evict any personnel found in the area. This is to prevent unnecessary exposure from beam induced radiation or, in certain areas like the FRIB linac tunnel, from x-ray radiation.

Throughout each area, there are a series of arm buttons placed in strategic locations along with gates/doors with associated switches. When securing an area, operators must go through and correctly push the arm buttons and close and doors and gates in the correct sequence as they search for any occupants. When this is done correctly, this will signal to the PPS that the area has been secured and is ready for beam operation.

An operator must have either attained the relevant competencies on Enterprise or be escorted by a fully trained operator to perform a search and evict procedure.
