| 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. 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. | 1) Re-activate the cooling water loop pumps. The controls are located at the entry to the source area.

| 2) Check the vault cryopump compressors to verify that they have re-started. There is one in the high energy pumping station and one next to the low energy pumping station. If they are running they should be making noise and the pressure gauge should read ~300 psi on the HE unit, and ~75 psi on the LE unit. If they are not running try cycling the power switch on the front of the compressor, if that doesn’t work try cycling the breaker on the back of the compressor. | 2) Check the vault cryopump compressors to verify that they have re-started.
