Uraguchi, K. Tanaka, Simon, Akutsu in the afternoon

We have successfully installed the TMS-VIS into the EYT chamber. We did it (Fig 3)!

• Uraguchi-san attached six geophones to the TMS-VIS.
• Along with the work, I checked resistors of all the coils and it seemed ok (memo: the following table I measured).
• Then we craned the TMS-VIS with four belt-slings (Fig 1), and broght into the EXT chamber.
• We also fixed some of the fixing bolts (Fig 2).

The installation was originally planed tomorrow; we did faster than our schedule.) We will install the BRT part on the TMS-VIS tomorrow.

Table to show my measurement. The nominal values should be

• LVDT inner coil: 210 ohm, 67 mH
• LVDT outer coil: 180 ohm, 42 mH (see for example here)
• Act coil: 133 ohm, 55 mH (see for example here)

Note that two "LVDT outer coils" are parallelly connected to pin 2-7, so the nominal values of them should be half of the above.
