== Today's activities ==
Workers: Miyo, Simon, Akutsu
 * Detached the protectors and the WAB got released.
 * Checked the balance or alignment of the suspended WAB with using a laser marker (レーザー墨出器).
  * Pitch was checked by illuminating the suspended WAB's top and bottom from the side.
  * Roll was checked by illuminating the suspended WAB's middle line from the side so that the laser beam can reach the other side; using the screw holes for fixing the temporal oplev reflectors, the WAB seemed to be rolled slightly. No one knows this rolling existed in Mitaka, as no one checked it with this equipment. Anyway the amount is not so large as reported [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4126|here]].
 * Resolved an issue about data transfer from the cryocon to KAGRA CDS EPICS; see [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4125|here]].
  * Now the temperature data is accessible from KAGRA CDS; for example, see [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4127|here]]. 
 * '''[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; especially in '''''YAW'''''.
 * 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.
 * Wash the coil in ethanol at Univ. of Toyama...?
 * 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.
 * '''''Chain block?''''' to support the load in the chamber.
 * A clock to know the time easily.
 * M6 screw set.
