Setting of PI
[Takahashi, Shimizu, Fujii]

1) Exchanged the blade for additional FR to F1 type.
2) Decompressed six blades for TF to +/-0mm.
3) Lifted up the PI from 176mm to 190mm by the jack with the cone bellows.
4) Changed the height of keystone from -6mm to -20mm to compensate the lifting up of PI.

The gap between the EQ-stop ring to BF body was following:
before this adjustment: 63.3 mm (average of 3 points, 61.5 mm, 62.0 mm and 66.5 mm)
after the adjustment: 63.4 mm (average of 61.8 mm, 62.0 mm and 66.5 mm).
This adjustment did not change the position of BF, for some reason BF seemed to be tilted in roll though..

[Note]
1. For the time being, the primary coil holder of BF-LVDT-H2 (of ITMX) is close to the secondary coil (figure 1). this will be tuned somehow after all the suspension is released.

2. For some reason, the current limit was working at the ITMX-digital rack today, I turned off an AI chassis for cryopayload-blade (see figure 2). after an installation of additional power supply, soon this will be turned on again.
