-This process will guide the operator through the steps to recover from a brief ( less than 1 minute ) power interruption.  ​The goal is to quickly restore critical support systems before they reach an inoperable state.  ​This process ​should ​take less than 3 minutes.+The source vacuum controls and cooling water pump switches are kept in an "​on"​ configuration by a UPS located on the sputter source vacuum cabinet.  ​The UPS should ​keep these controls running for 30-40 minutes.  The pumps themselves will thus restart automatically when the power comes back on, as long as the UPS is still working.
  
 If a power blink is observed, or the phase alarm activates, immediately follow these steps as soon as the power comes back on: If a power blink is observed, or the phase alarm activates, immediately follow these steps as soon as the power comes back on:
  
-1) 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.  ​+1) The source ​cooling water must  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.

-  +3     ​Acknowledge ​the alarm panel, reset the shutdown module ​and the tritium monitor. 
-  + 
-  +4) If the blink was more than a few milliseconds ​the accelerator ​and all electrostatic devices will have shut down and all electrically operated gate valves (except for the sources) will have closed.  If the accelerator was running, ​set all of its controls to the initial condition (offsettings.   
-  + 
-3) Proceed to the mechanical room.  ​Stand at the yellow circle painted on the floor in front of the main breaker panel. ​ Push the reset and start buttons on panels A, B, & C.  This will activate 2 air handlers, and the water pump behind you. +5     Check the “main loop temp” on the alarm panel. ​ If it is greater than 58 the chiller has failed and you will need staff to restart it.  ​Turn down the magnets. 
-  + 
-  +6) Return to the vault and check that the 4 cryopumps ( LE line, LE pumping station, HE pumping station, analyzer line) are still cold.  ​The CTI pumps at the LE area have reliable temperature gauges. ​ Condensation or frost on the cryopump ​is a sign of failure. ​ If they appear to still be good open the "​pump"​ gate valve at each pumping station.  If they have failed, shut down the compressor to begin regeneration, do not open any gate valves.  
-  + 
-  +7) The HVAC, lab cooling water, and compressed air systems are automated and should return to normal operation within 5 minutes of power restoration. ​ No action is required in the mechanical room upstairs.

- Panels A, B, C Water pump +8) This process has preserved the vacuumcooling, climate control ​systems. ​ The ion gauges, gates valves and ion sources will need to be carefully re-started to resume operations. ​ Call the lab staff personnel for assistance in these matters.

-4) Return to the control room.  ​Check the “main loop temp” on the alarm panel. ​ If it is greater than 50 the chiller has failed and you will need staff to restart it.  ​Do not re-start the accelerator,​ and turn down the magnets. +
-5) Return to the vault and check that the 4 cryopumps ( LE line, LE pumping station, HE pumping station, analyzer line) are still cold.  ​Remember, ​the green part of the dial is NOT good.  If they have failed, shut down the compressor to begin regeneration. +
-6) This process has preserved the vacuum ​and cooling systems. ​ The ion gauges, gates valves and ion sources will need to be carefully re-started to resume operations. ​ Call the lab staff personnel for assistance in these matters.+
