The LLL 2xIIB experiment is briefly described. The vacuum system uses mercury diffusion pumps and titanium sublimation. The base pressure of the guard vacuum is about 10$sup -5$ torr and about 2 x 10$sup -7$ torr in the high vacuum space using the diffusion pumps only. After titanium sublimation, the high vacuum pressure drops into the 10$sup -9$ torr range. A procedure for leak testing using a special sniffer probe is described. (MOW)
