Today's activities
Workers: Akutsu, K. Nagano, Aritomi K. Tanaka, Kita
- Delivered an oplev pylon.
- Delivered a K400 flange (VN7877 by Mirapro), which had been washed at Mirapro.
Checked the polarity of LVDTs and actuator coils, and compared with the one measured in Mitaka shown here.
When we took up the side of the table where LVDT-V1 was installed, the raw LVDT-V1 signal (VIS-TMSX_LVDTINF_**_INMON) showed minus signal; in the same manner, V2-> positive, V3-> negative, and all the horizontal signals (H1,H2,H3) were positive; they were consistent with those of in Mitaka.
Next plan
- Connect the cables to flanges.
- Configure the digital models properly.
- Engage the logical channels and the assigned physical channels.
- Install BRT on TMS-VIS.
Clean the sides of the optics to be installed into the vacuum chamber. (Ethanol+Acetone wiping with vectra alpha, then First Contact.) See here.
- Detach the remaining white tapes just before closing the chamber; be noted that there are white tapes on the PEEK connectors at the inside of the flanges.
- Torque completely the bolts which are fixing the upper and the lower base plates.
- Insert metal gaskets before torquing the ICF203 flanges with Dsub connectors.
- Make clean the cabling... ask to VIS??
- Check horizontal actuation
- Calibrate LVDT again
- Put calibration factor of Geophones
- Install Tome-Kanagu for Dsub in DAC0 port #4
- Put tags to cables
- Align BRT
- Start to install GPT part
- Damping of TMS-VIS
Wanted!
- Tester!! lend from DGS or PEM??
- M8 eyebolts for managing the dummy weight plates...
- First contact to clean the side diameter of the optics.
- Need a signal generator for LVDTs
- A document for learning how to release or fix the suspended tables (by Uraguchi?).
- Cable tags
- IR mirrors (4 PYD-20, 3 PYD-10)
- Tome-Kanagu for Dsub
- Power taps
- ONE DAC PORT!!!!
