CX-011684: Categorical Exclusion Determination

Operation of the 50 MeV Electron Linac Accelerator (CSE60)
CX(s) Applied: B3.10
Date: 12/12/2013
Location(s): Illinois
Offices(s): Argonne Site Office

The 50 MeV Linac electron accelerator is an existing facility that is used by CSE division to study radiation induced effects in solid, liquid, and gaseous samples. The Linac accelerator facility is located in Building 211, room D-076, and utilizes a closed loop cooling water system and a one pass air ventilation system. The energy of the generating electrons is high enough to induce radioactivity in accelerator components (beam pipes, magnets, and beam stops) but direct interaction of the high energy electrons with air does not effectively activate the air due to the small cross section.
