The gas system has been checked. The variable valve opens at about 7.55 very fast. Please be careful when using it. Stepsize for opening around this value should be 0.01. Gas lines have been pumped with pump in the high voltage rack. Ne leak was opened to release pressure.

turbo pumps shut off due to work on cooling water system

  30   Tuesday, January 24, 2012, 09:44 Friedhelm Ames       turbo pumps restarted

All turbo pumps have been restarted after cooling water is back and running.

Both turbo pumps at the source box were found off. TSG:TP1A has been started normally. TSG:TP1B does not spin up above 3KRPM even after several attemps. A fault report has been send to vacuum group.

 after about 30 minutes running at normal speed TP1A failed as well. Both pumps will be kept off over night.
