The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today.  5psi helium gas was applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to the matching connector inside the cell.  The end of the wand was sealed using tape.  The Agilent G8601 leak detector was used on "sniffing" mode to check for escape of helium gas from all joints and connectors.  With the sniffing line attached the leak detector test port pressure was 3.9E-1 Torr and the baseline leak rate was 1.7E-6 Torr*L/s.  There was no response while testing all of the three lines.  For all three there was a leak detector response after disconnecting the Staubli fitting, which confirmed that the lines were properly charged with helium.
