    keyword=Detector gas system status

    The nitrogen for the pneumatic valves ran out. It would seem one of the check valves in the system is leaking. I replaced the cylinders and recharged the system. All gas is back on line. I moved the gas supply line for the NaI back to the manifold normally used for the RICH methane supply. We will continue to use the RICH manifold for the NaI. This will prevent this from happening again. The gas flow was down for a short period. I do not expect any effects to be seen in the VDCs. Do not make any unauthorized modifications to the gas systems.
