 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 (off) settings.  ​ 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 (off) settings.  ​
  
-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. +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.  ​Check the status of the magnets. Each magnet control module should be showing a red light for standby or off condition. Magnet current meters need to be showing zero amps. Turn down the magnets ​if they are not at zero.      ​

 6) Return to the vault and check that the 4 cryopumps ( LE line, LE pumping station, HE pumping station, analyzer line) are still cold.  All pumps 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. Shut down by the yellow breaker on the rear of the compressor. 6) Return to the vault and check that the 4 cryopumps ( LE line, LE pumping station, HE pumping station, analyzer line) are still cold.  All pumps 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.
