Today's activities

Workers: Simon, Akutsu

  • Replaced a tentative breadboard supporting photosensors, a coil, and a burndy connector with a small but vacuum compatible one; see here.

    • As described in the above link, the breadboard got rust during the natural dry after washing, so the rust was polished out and then again washed.
  • Relocated the photosensors, the coil, and the burndy connector.

  • Measured with the coil injection; see here; needs more analysis.

  • [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 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.
  • Check heights of several points.
  • Take care of water spring??

Wanted!

  • Two burndy connectors, vacuum compatible.

  • Stages outside the chamber to ease wiping our legs.

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

  • Chain block? to support the load in the chamber.

  • A clock to know the time easily.
  • M6 screw set.
