keyword=Detector gas systems shut down
Yesterday I shut down the FPP gas system. No gas is flowing. For the VDC
gas system I bypassed the ethanol bubbler and purged the ethane gas
lines. The VDCs now have pure argon flowing through them. The
carbon-dioxide flow to the Gas Cerenkov counters was turned down to about
1/3 of what it was. The VDC high voltage power supplies were switched off
and should remain off until ethane and ethanol are again connected to the
VDC gas system.
