  • Content Description: This paper is a sequel to the one prepared by Atkinson, et al., in which the authors described the vacuum system of Lawrence Livermore Laboratory's Tandem Mirror Experiment (TMX). We discuss here the final configuration, liquid nitrogen (LN/sub 2/) supply, and operation of the complete TMX vacuum system. The assembled vacuum system consists of two plug tanks with a volume of approximately 60 m/sup 3/ each and a center cell tank with a volume of approximately 10 m/sup 3/. In each plug tank there are 145 m/sup 2/ of titanium-gettered, LN/sub 2/-filled panels, which allow a pumping speed calculated to be 5 x 10/sup 7/ l/s for a period of 50 ms. The system maintains an operating pressure in the plasma chamber on the order of 10/sup -6/ Torr while 24 neutral-beam injectors are introducing 700 Torr l/s of hydrogen into the vacuum chamber.
