Abstract

The Tritium Pellet Injector (TPI) is a cryogenic pellet injector which will be used on TFTR prior to and during the D-T phase of operations. The injector will replace the current Deuterium Pellet Injector (DPI) at Bay T with an injection capability for pellets of deuterium and/or tritium or mixtures of both. The gun will be a 4 barrel configuration (replacing the existing 8 barrel system) with one of the barrels capable of high speed. Pellet acceleration will be accomplished pneumatically using high pressure helium and hydrogen gas. The injector has one cylindrical pellet per barrel per shot with each barrel independent of the others. Velocity of the pellets when they are injected into the plasma for the single stage gun will be 1.5 km/sec which is variable from .5 to 1.5 km/sec. For the Two-Stage gun velocities will be 3.0 km/sec.
