== Today's activities ==
Workers: Simon, Miyo, Akutsu
 * Continued to calibrate the photosensors.
  * With different current sources to the LEDs; OSEM satellite box and Agilent F3630A; the calibration factors seemed to change just according to the supplied current; see [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4246|here]]
  * About the issue yesterday, we found the difference of the calibration factor shapes were not due to the difference of the reflectors surface; see [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4249|here]]
   * Why...???
 * Determined our mind to install the photosensors anyhow.
 * Locked the suspension.
 * Installed the heat-link anchor block and all the heat links, finding nice/good alignment of the heat links... see [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4242|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.
 * 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.  
 * Check heights of several points.
 * Take care of water spring??

== Wanted! ==
 * Two burndy connectors, vacuum compatible.
 * '''''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.
