Abstract

The ability to increase the quantity of lithium deposition into TFTR beyond that of the pellet injector while minimizing perturbations to the plasma provides interesting experimental and operational options. Two additional lithium deposition tools were developed for possible application during the 1996 Experimental Schedule: a solid lithium target probe for real-time deposition, and a lithium effusion oven for deposition between discharges. The lithium effusion oven was operated in TFTR to deposit lithium on the inner limiter in the absence of plasma. This resulted in the third highest power TFTR discharge
