== Today's activities ==
Workers: Akutsu, Simon, Miyo
 * Continued to check the balance or alignment of the suspended WAB with using a laser marker (レーザー墨出器), and the procedure foreseeing the actual installation and integration of the WAB suspensions.
  * '''''Detail of the results will be reported later...'''''
 * Tested a photosensor (PS) head. It seemed works; need to do more to make a meaningful report.
 * '''[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 ==
 * Wash the coil and the PS parts in ethanol at Univ. of Toyama...?
 * Complete the assembly of the PS heads with clean parts (or wash them after assembled)
 * Make some patch cables to connect Dsub and the distributor for the PS.
 * Calibrate the PS.
 * 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.  
 * Prepare calibration of photosensors.
 * Check heights of several points.
 * 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.
