LHe Usage

Cool Down of 12/97

The above linear fit yields a usage rate of 0.1389 inches per hour. Since the reservoir is approximately 15" high - this implies a hold time of 108 hours or 4.5 days. The scatter around the straight line fit is due to the fact that we were running extensive tests of the 3He system. The usage rate was highest during the day when we were running the pumped pot and heating the charcoal pumps extensively.
