Operators: zhangchi ---- ----

first half of the shift very smooth. WC temperature is fine, Even WC L14 had been holding at 3800. Just when I thought nothing would go wrong ...

4:20, ROCR stopped to respond, after failed to reboot it from counting bay, power recycled the crate in Dtunnel. ROCR failed to respond again an hour later. Had to go to Dtunnel again. Dtunnel is extremely warm, decided to leave the door open for a while.

Came back to find dblast07 scratch full. erased 7400 series runs after making sure these runs are also on spud4.

before one single run finished after cleaning up disc, beam became problematic. Same sympton as last night. a few minutes after the fill, beam current drops steeply and cause trips in TOF/LADS/WC HV. CC lowered max beam current to 105mA.
