 The Operator should take the following actions after power is restored: The Operator should take the following actions after power is restored:
  
-1)  Silence any alarms that have activated +1)     ​Silence any alarms that have activated, E1/E2, shutdown module, tritium monitor.
-2)  Notify Accelerator Staff of the situation +
-3)  Re-activate the cooling water loop pumps. The controls are located at the entry to the source area. (Ground the high voltage cage). Push each start button. The source cooling water must also be re-activated. This control is on the side of the cabinet that is against the wall by the sputter source. You may need to hold the “on” switch for several seconds before the pump will remain on+

-4)  ​Check the status of the vault cryopump compressors. There is one in the high energy pumping station and one next to the low energy pumping station. If they are running, turn them off.  Red toggle switch on the front of the HE compressor, yellow breaker on the rear of the LE compressor.+3)  ​Notify Accelerator Staff of the situation
