Early turn on of STOF and SEM electronics 10 & 23:10 # CELIAS # 1.04: STOF and SEM electronics turn on # 0:50, no contingency included in this time, non-ops heater for STOF and STOF/E off (this is not STOF bakeout), SEM turn on requires STOF in Manual Mode, this sub-block should only take place after 1.03 is complete, Procs and NRT-d ; DAY 14 ; *REQUEST FOR REVISION * DAY CHANGES! ; STOF initial turn-on now on day 10. ; STOF IFC checkout moved to day 24. ; Changes in STOF SSD background check both before and ; after shutter release but before bakeout requires that the ; STOF SSD checkout (shutter closed) should be done as early in ; the day 14 as possible, with a minimum of 2 hours before STOF shutter release, ; but no more than 4 hours with the test generator on. After shutter release, ; another SSD background (shutter open) , again minimum 2 hours, but 4 hr maximum with ; test generator. Then bakeout with STOF SSD off. ; Remember MTOF off for shutter release and must be returned to MTOF bakeout ; configuration after shutter open. ; REQUEST FOR REVISION * TIME CHANGE! 14 & 09:00 # CELIAS # 1.05: STOF SSD Check-out (Closed) # 1:00, as early as possible in the day of the shutter release in order to finish blocks 1.05 through 1.08 in one day, Procs and NRT-d ; * REQUEST FOR REVISION * TIME CHANGE! 14 & 14:00 # CELIAS # 1.06: MTOF off and STOF Shutter Release # 0:50, must be same day as 1.05, but about 2 to 4 hours in-between, Procs and NRT-d ; * REQUEST FOR REVISION * NEW SEQUENCE!

Since MTOF operational turnon is ; delayed until after MCC2, continue MTOF bake out until preparations for ; MCC2 on day 18.

CTOF wants to contiue bakeout ; after MCC2, and delay the initial configuration accordingly. MTOF ends ; bakeout. Heaters should be off for manuever MCC2, since commanding not possible ; for thermal control. 18 & 12:40 # CELIAS # 5.01: Pause in CTOF bakeout because of MCC2 # 0:30, Procs and NRT-d 18 & # CELIAS # 1.13 MTOF End Bakeout # 0:30, before 5.02 (MCC2 preparation) or incorporated with 5.02, Procs and NRT-d 18 & 14:40:05 # CELIAS # 5.02: CTOF, MTOF, STOF to Standby for MCC2 # 0:30, Procs and NRT-d ; DAY 21 ; * REQUEST FOR REVISION * CTOF requires additional bakeout time. 21 & # CELIAS # 5.03: Resume CTOF bakeout after MCC2 # 0:30, assumes experiment commanding allowed on day 21, Procs and NRT-d ; * REQUEST FOR REVISION * STOF and MTOF need to return to pre-manuever configuration 21 & # CELIAS # 5.04: MTOF, STOF Return to configuration after MCC2 # 0:30, Procs and NRT-d ; MILESTONE BLOCK 5.0 for manuever MCC2 completed. ; DAY 22 ; * REQUEST FOR REVISION * MTOF requires additional HV turn on time, over at ; least nine days, as originally requested in the CELIAS 4.0 timeline. ; Request 3 hour period on day 22, does not need to be all at one time, but ; at least 30 minute command intervals. 22 & # CELIAS # 2.01 MTOF Initial Configuration # 0:20, Procs and NRT-d 22 & # CELIAS # 2.03: CELIAS/MTOF INITIAL HV TURN ON # 2:30, Procs and NRT-d ; DAY 23 ; * REQUEST FOR REVISION * ADD COMMAND TIME!
