Low Pressure alarm sounded for the Detector Gas System Interlocks
(accompanyied by strange readings for the Argon/Ethane/Co2 pressure
readings on Hall A General Tools: Argon = -28psi, Co2 = -45 psi, and
Ethane=193 psi). Bob went to investigate in the gas shed; the gas
bottles all look full (they were swapped out by Jack earlier this morning
during fixing of the initial problem), but it seems like some valve has
closed ... Jack Segal is on his way over to check it out. We continue
data-taking, since such gas-flow problems have a long enough time
constant before impacting the chamber efficiencies.
