This is a BS-212 Anton counter shell converted to a UV corona lamp. This was used during the 1950's for field checking the sensitivity of UV detectors used in Naval Research Laboratory programs. This artifact is part of a collection of high energy detectors from the Naval Research Laboratory (see A19880001000-19880017000).
It was transferred to NASM in 1987 and is currently stored at the Garber facility.
