Today's activities

Workers: Akutsu, Simon, Miyo

  • Continued to check the balance or alignment of the suspended WAB with using a laser marker (レーザー墨出器), and the procedure foreseeing the actual installation and integration of the WAB suspensions.
    • Detail of the results will be reported later...

  • Tested a photosensor (PS) head. It seemed works; need to do more to make a meaningful report.
  • [Ongoing] Need cares of water springs from anchor bolts for oplev pylons.

  • [Ongoing] Need to confirm what are the scratch lines made by the measurement by the KEK team last week.

Next plan

  • Complete the assembly of the PS heads with clean parts (or wash them after assembled)
  • Make some patch cables to connect Dsub and the distributor for the PS.
  • Calibrate the PS.
  • Complete the calibration of the oplev; the arm length was reported by Simon, so....
  • Check the balance of the suspended WAB with some wires and sensors are attached.
  • Check how the damping would be now after the replacement of the damping magnets.
  • Check the reproducibility of the alignment of the suspension among several modes.
  • Prepare calibration of photosensors.
  • Check heights of several points.
  • Take care of water spring??

Wanted!

  • A tweezer.
  • Two burndy connectors, vacuum compatible.
  • Chairs in the clean booth
  • Cutters and scissors!!
  • Stages outside the chamber to ease wiping our legs.

  • Good rail(?) to move the WAB suspension in the cryostat in the main beam direction.
