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.

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??

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.
