- Preparation
Make marks on FFU switches that are not turned off in MCE, IFI, PRM, PR3, PR2, BS, SR2, SR3, SRM, OMC with "GreenTape".
(Operated FFU / Total FFU) table list is below.
130 FFUs will be turned off. This corresponds to 26kW heating power.
26kW corresponds to about two water cooler cooling power (2 x 14kW). We expect balance.

IEXYV
- Take a sensitivity by an operator (one of PEM member). (Miyoki, Yokozawa, Washimi)
Each 2 people stand by IEXYV FFU switchs. (Team1-> EXV, Team2 -> EYV, Team3->IXV ,Team4->IYV)
Turn off remained two FFUs at the same time. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- Take the sensitivity again before alignment will change. (Miyoki, Yokozawa, Washimi)
Turn on two FFUs that used to be turned on. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- If you see any change in sensitivity, we recheck one by one for IEXYV.
IEXYC(1/2F) and Transmission Area
- Take a sensitivity by an operator. (Miyoki, Yokozawa, Washimi)
Each 2 people stand by IEXYC FFU switchs. 10 are near the KOACH, 14 near the Transmission area. (Team1-> EXC, Team2 -> EYC, Team3->IXC ,Team4->IYC)
Turn off remained FFUs at the same time. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- Take the sensitivity again before alignment will change. (Miyoki, Yokozawa, Washimi)
Turn on FFUs that used to be turned on. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- If you see any change in sensitivity, we recheck one by one for IEXYC-1F/2F.
IEXYA
- Take a sensitivity by an operator. (Miyoki, Yokozawa, Washimi)
2 people stand by IEXYA FFU switchs. (Team1-> EXA, Team2 -> EYA, Team3->IXA ,Team4->IYA)
Turn off remained two FFUs at the same time. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- Take the sensitivity again before alignment will change. (Miyoki, Yokozawa, Washimi)
Turn on two FFUs that used to be turned on. (Yokozawa -> Team1, Washimi -> team2, Miyoki -> Team3,4)
- If you see any change in sensitivity, we recheck one by one for IEXYA.
For Corner station 1F
- Method(1)
- Take a sensitivity by an operator. (Miyoki, Yokozawa, Washimi)
- 11 people stand by (MCE, IFI, PRM), (PR3, PR2, BS), (SR2, SR3), (SRM OMC), and Pre-Room FFU switchs.
- Turn off almost FFUs at the same time by 11 people, except for Green one.
- Take the sensitivity again before alignment will change. (Miyoki, Yokozawa, Washimi)
Check the difference btw FFU operation and almost no FFU operation.
- Method(2): If the alignment change is too huge for us to take a sensitivity.
- We turn off IYC-C and BS-C coolers at the same time when we turn off 130 FFUs.
- Take sensitivity urgently if possible. (Miyoki, Yokozawa, Washimi)
- Check the temp changes in the corner station.
- If the temp seems to go down rapidly, we enlarge heating power. If the temp gose up rapidly, we turned on IYC-C again and heat up by heaters.
- we expect do some try and error for several hours if we encounter serious temp change.
- If alignment comes back, take sensitivity. (Miyoki, Yokozawa, Washimi)
- If it will take too much time to recover FPMI, we give up this trial.
- Method(1)
Vacuum pump stopping`
- We want to stop vacuum pumps one by one
- FFU would be turned on
- If temperature or vacuum pressures drastically changed, the experiments stopped
- two people for Xend, two people for Yend, Four people CS
- Stop the Vacuum pump one by one with instruction of Miyoki-san or Saito-san
- Maximum experiment time is two hours or 5p.m.
