  * Re-did the cabling of BNC cable around the rack

20181010

Today's activities

Workers: Akutsu, Michimura, K. Tanaka (10:30-21:00)

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.

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 (with ceiling LED lights on). Green beam moves a lot.
    • I was amazed by how well the cabling was done! We could also see the singal with MEDM screens without any problem.
    • The Dsub cables go under the optical table to QPDs.

AOS_TMSX_GR_QPD

  • Aligned beam to green DC PD to maximize the signal (~12 counts (~6 counts background with ceiling LED lights on)).
    • Re-did the cabling of BNC cable around the rack
  • 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). The green beam looks clipping somewhere (output of BRT is already dirty).

TMSX_G

  • Fixed MEDM screen for camera name change, and added a button for GR_PD.

AOS_TMSX_OVERVIEW

  • Installed IR periscope.

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.

  • 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
  • Measure the length between BRT lens3 and GLNS1

Wanted!

  • Screws to screw Dsub 15pin connectors to QPD amplifiers
  • Nice way to turn off the ceiling LED light
