== Progress report ==

=== General topics ===
 * VIS Guardians are under renovation.
  * They use unified state names among the different suspension types.
 * New damping strategy ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12368|klog#12368]]) 

=== Type-A ===
==== Past week report ====
 * Terrence's paths implemented in the RT models.
  * They are working will in ASC.
 * High power coil drivers for TM actuators installed with WD disabled.
  * Only ITMY is still not ready. → Next week
 * Actuator balancing performed.
  * ITMX: [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12348|klog#12348]]
  * ITMY: [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12350|klog#12350]]
  * ETMX: [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12347|klog#12347]], [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12426|klog#12426]]
 * Local damping control updates
  * ITMX pitch RMS motion drastically improved. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12353|klog#12353]])
  * BFL feedback loop could damp the ~0.97 Hz longitudinal mode ([[|klog]])
  * Photo-sensor damping loops under implementation.
   * Besides that, PS efficiency balancing and decoupling ongoing.
 * Some GAS controls got saturated again due to the temperature drifts. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12379|klog#12379]])
  * We left them as they are for the moment and expect that the temperature adjustment could recover the better situation again.
 * OpLev light sources replaced in ETMX and EMTY. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12440|klog#12440]])

=== Type B ===
==== Past week report ====
 * Local damping control updates
  * BS IM pitch loop modified. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12353|klog#12343]])
 * SR2_IM picomotor got lost in the control network. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12403|klog#12403]])
  * The IP address of its driver was reset with wired connection. 

==== Plan for coming weeks ====
=== Type-Bp ===
==== Past week report ====
 * PR3 was kicked due to the length control. Health check was done, and we found that PR3 seems to be rubbing a bit. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12396|klog12396]]
  * We will see how it goes with this situation, since there is no problem so far even it is not in a good state.
==== Plan for coming weeks ====
=== OMMT & OSTM ===
==== Past week report ====
 * Glued magnets and standoffs to the mirror and installed the mirror to the suspension.
 * Since one magnet was took off during the adjustments of OSEMs, the mirror went to regluing.
