The laboratory space in B037 includes a large cleanroom facility which was initially used for the SNO NCD counter production. It has since been used for efforts including the Majorana Demonstrator component clean materials R&D, testing, and production, as well as for the TRIMS apparatus assembly. The cleanroom is rated class 100 and is cleaned monthly by CENPA hourlies. Current outfitting includes a deionized water supply, small (~1/2 L) sonicator, N2 and He gas lines, N2-purged dry-box, and clean soldering station. Its anteroom is rated class 1000.
