GPT part installation
- Other things
- LVDT driver was not working properly last night because the power cable for SG generating 10kHz calibration line for LVDT was accidentaly unplugged. We taped the cable to the reel.
- Height of the BRT output beams to TMSX table was re-adjusted with HBS and GST0, using a laser leveler, so that output beams are parallel to the ground.
- Plugged Dsub cables to green QPDs, and roughly centered. It moves a lot.
- I was amazed by how well the cabling was done!
- Kokeyama-san and T. Yamamoto-san fixed the network issue and Gig-E camera now works. We renamed the camera from BRTX_G(and BRTX_IR) to TMSX_G(and TMSX_IR).
Next Plan
- Align and balance the BRT and the TMS-VIS.
- 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.
- Modify MEDM screen
- Add DC PD and so on.
Cable Dsub 15pin for TMS-VIS OpLev.
- Modify cabling for DC PD.
- Return plastic box.
- Install rails in digital rack.
- They may be necessary under LVDT distributor, geophone distributor, and WHT board.
- Nagano is not sure it is necessary under HP coil driver.
- Consider how to cable Dsub cables to QPD.
- Install IR optics
