Today's activities

Workers: Akutsu, Simon, Miyo, Hasegawa, T. Yamamoto with helps by Miyamoto

• Continued cabling outside of the clean booth (Yamamoto, Miyo, Simon)
• Installed an oplev viewport in the -X-Y direction (Hasegawa)
• Practiced to connect a burndy receptacle terminal to an electric wire AWG36 (Akutsu); in the afternoon Miyamoto showed us his well-trained technique. Thanks!
• With all above, connected a thermometer in the cryostat to a cryocon outside of the clean booth; now the temperature can be read from the cryocon even via network!
  • Miyo just tried to heat up the thermometer by his temperature and it worked (?).
• Installed the digital system; connected an oplev in the booth, and now the signal can be read via the digital system.
  • Note that the pylons are still not rigidly fixed on the floor; don't forget it.

• [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

• Set up thermometers; especially their pins.
• Set up oplev to 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.
• Connect burndy pins to the heaters??
• Check heights of several points.
• Wash the coil in ethanol at Univ. of Toyama...?
• Take care of water spring??

Wanted!

• A tweezer.

• 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.

• Cutters and scissors!!
• A clock to know the time easily.

• A fiber cleaner to connect oplev source parts; need to get back from Yend.

• M6 screw set.
