== 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.

 * 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.

 * 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).
  * The height of Gig-E camera is also adjusted

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

 * Installed IR periscope.

== Next Plan ==
 * 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.
 * Attach an oplev viewport
 * Setup the oplev for TMS-VIS
 * Consider why the green ghost beam is not observed; that was observed in TMSY in this April.

 * Modify MEDM screen
   * Add DC PD and so on.
 * Cable Dsub 15pin for TMS-VIS OpLev.
 * Return plastic boxes.
 * 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! ==
 * Black tubes attachable to the DC-PDs or seetabale in front of the DC-QPDs for light shielding.
 * Screws to screw Dsub 15pin connectors to QPD amplifiers
 * Nice way to turn off the ceiling LED light
 * Covers for cables running on the floor
 * Shield box against environmental light
 * Wind shielding... (it would be somewhat difficult as two beams are running in the different directions from the viewport window)
