Vacuum system for the Tandem Mirror Experiment
The Tandem Mirror Experiment (TMX) under construction at LLL is a Q-enhancement experiment using two mirror fields to ''plug'' a central solenoid field. Neutral beam injection supplies the energetic neutrals to the plug regions with attendant quantities of cold gas. The vacuum vessel consists of two large stainless steel tanks, which house the plug coils, joined by an aluminum central cell tank, which fits inside the existing solenoid coils from the 2XIIB experiment. The plug tanks are subdivided into regions for differential pumping of the source gas by liquid-nitrogen- or water-cooled liners. The liners are gettered by Ti--Ta wire sublimators of the 2XIIB type, using 2XIIB power supplies, to supply the necessary high-speed surface pumping. The roughing vacuum system consists of mercury vapor diffusion pumps backed by Roots-type blowers.
