-===== 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 "emptied" status described in Wiki 
-  * 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
