Tri Alpha Energy requires a large pumping speed of approximately 2 million L/s for hydrogen and 1.5 million L/s for deuterium in each of the four divertors (22,000 L) on C2W. To accomplish this TAE has developed a liquid nitrogen cooled, titanium getter pump. The experimental pump speed was tested for a variety of parameters including purity of titanium (99.995% and 99.97% Ti), various temperatures, and saturation. Purity of titanium showed no effect on the pump speed but there was a clear correlation with the temperature and saturation. With this, TAE had discovered a regime of operation during plasma shots in C2W.
