== Today's activity ==
Workers: Akutsu, Simon, Miyo, Hasegawa
 * Received the WAB suspension at the tunnel entrance and brought it into the IYC clean booth with helps by Furuta-san and Nakada-san, and management of Uchiyama-san.
  * Thought we must need '''''new handles''''' for easier transporting the WAB suspension for the future; today we managed somehow.
  * Found bedewing (condensation of water) on the WAB suspension as predicted; gently covered some flat sections of the suspension with vectra10, and left it; in a few hours the dews disappeared.
 * Brought some measurement instruments into the IYC clean booth; they were:
  * a tripod stand (from TypeB)
  * a laser marker (from TypeB but from KEK-GR)
  * two bubble levelers (from TypeB)
  * a height gauge (from TypeB)
 * Brought two burndy cables (one of the two is from IXC) into the clean booth.
 * Brought two heaters each of which is attached to an aluminum plate (Simon delivered with him)
 * Brought a current source (from IXC) near the booth.
 * Brought a tool box (from IXC) near the booth.
 * '''[Ongoing]''' Need cares of water springs from anchor bolts for oplev pylons; '''''ongoing'''''.
 * '''[Ongoing]''' Need to confirm what are the scratch lines made by the measurement by the KEK team last week.
 * Slightly checked the tilt of the basement optical table located in the IYC chamber with a bubble leveler (mentioned above) by Akutsu; it seems nice; the bubble leveler shows it can measure 0.5mm/1m tilt on its body.
 * Wanted '''''cutters and scissors!!'''''
 * Wanted a clock to know the time easily.
 * Wanted/needed a fiber cleaner to connect oplev source parts; '''''need to get back''''' from Yend.
 * Wanted M6 screw set.

=== What Simon delivered with him ===
 * six thermometers; stocked in a plastic box at the entrance of the IYC clean booth.
 * The metal.
 * a coil
 * several nuts
 * two heaters (as mentioned above.)

== Tomorrow's plan ==
 * Pick up a QPD board for the oplev!
 * Pick up OptoSigma parts sent to Akutsu.
 * Pick up parts sent to Simon.
 * Try to locate the WAB suspension to its nominal position.
 * Take it back to the table and detach some guard parts and check the balance, and attach them back;
 * Attach heater plates?
 * Try to connect bundy pins to the heaters??
 * Place bundy cables toward outside?
 * '''[Slightly done]''' Check tilt of the basement optical table in the IYC chamber.
 * Check heights of several points.
 * Wash the coil in ethanol at Univ. of Toyama...?
 * Wash nuts in machine cleaner at Mozumi.
 * Take care of water spring??
