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

 || Area Name ||MCF || MCE || IFI || PRM || PR3 || PR2 || BS || SR2 || SR3 || SRM || OMC ||

   1.#2 '''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'''
    1.#2 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.  <<BR>>

    * 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.

   * '''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.
