NOTE: If cooling is required, the compressors will have to be run manually. Make sure to switch it off again when the water has reached an acceptable
temperature.
The staging did not work properly this morning. Dave Morris have been contacted and will look into it. |

No leak detected on either He-detector (connected directly to Service Cap) or on RGA. See attached screen shots.
A vacuum increase (air only on RGA) was seen when de-pressurizing circuit I. |

No Source Tray installed. Loop on cooling circuit D. All other circuits blanked off.
Voltages stated below are set point voltages. These corresponds reasonably well with the local read backs on the power supplies. The read back
voltages in EPICS are somewhat lower. |

|
See e-log entry for ITE for details. The copper bars have not been removed. They
can be used for testing the new power supplies.
Local measurement was done by Ray with a voltmeter. The voltmeter was consistent with EPICS readback and local readback on the power supplies. |
