| - | ===== Communication before and after completion of Shutdown ===== | ||
| - | * Give heads up to Operations (beam coordinator) | ||
| - | * Heads up to any experimenters planning to run in the vault | ||
| - | * Heads up to GRETINA group | ||
| - | * Heads up to Cryogenics group | ||
| - | * Heads up to Magnet group | ||
| - | * Make an entry in Hourlog indicating status of S800. Include also contact information. | ||
| - | * If possible, prepare and submit a Work-Control Plan | ||
| - | |||
| - | |||
| - | ===== Detectors ====== | ||
| - | * Turn off all GUI-controlled HV (including iSeg HV for hodoscope (crystal #20), located in S3 crate attached to FP chamber) | ||
| - | * Turn off power supply preamps and CRDC interface boards (same S3 crate attached to FP chamber) | ||
| - | * Turn off all manual HV in dU6 (OBJ SCI, CRDCs grid) | ||
| - | * Empty detectors and make sure that valves configuration matches " | ||
| - | * Close gas bottles and valves downstream of regulators | ||
| - | |||
| - | |||
| - | ===== Drives ===== | ||
| - | * Retract all linear drives | ||
| - | * Open beam blockers | ||
| - | |||
| - | |||
| - | ===== Vacuum ===== | ||
| - | * Close ALL gate valves | ||
| - | * VERY IMPORTANT: Vent FP box, but leave dry N2 flowing (it requires opening the lift-off disk of the pressure-relief valve) | ||
| - | * Make sure that FP Turbo-pump is OFF. Turn OFF Turbo Pump chiller | ||
| - | * Turn off CRDCs chiller | ||
| - | * Vent all sections, including Spectrograph (assistance from vacuum group will be needed). IF this is not possible, make sure that this section is isolated (close gate valves upstream and downstream) | ||
| - | * Make sure that all sections are at atmospheric pressure | ||
| - | |||
| - | |||
| - | ===== Magnets ===== | ||
| - | * Set all Brhos to 0 Tm | ||
| - | * Turn off all power supplies, including steerers | ||
| - | |||
| - | ===== Cryogenics ===== | ||
| - | * Notify (e.g. email) Cryogenics that all magnets are off | ||
| - | * Check if there is any He lead return pipe open. If so, notify Magnet group and/or Cryogenics group so they can close it at their earliest convenience | ||
| - | |||
| - | |||
| - | ===== Electronics and computers ===== | ||
| - | * Turn off all crates in S800 rack (S3 vault) | ||
| - | * Turn off all crates in dU6 | ||
| - | * Reboot s800fp PC (in S3) | ||
| - | * Reboot down u6pc5 | ||
| - | * Reboot down spdaq50 | ||
