As I tried to close the JT valve to relieve the CHL coolant drawing (at the time 24g/s) using the goto mode to position 62 (current position 63.4) the position went to zero (closed valve). The pressure of the cell dropped quickly to 16psi and the temperature to 93.80K since there was zero drawing from CHL.
Since no more He was in the bottle hoocked to the system in Hall A we could not recover (with the help of Jian Ping) from the counting house. Called Dave Meekins for putting a new bottle in the Hall.
