== Progress report ==
=== Type-A ===
==== Past week report ====

 * Yamada-kun made a control noise projection from Type-A payload actuators to DARM. ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12229|klog#12229]])

==== Plan for coming weeks ====

 * Real-time model update
  * To add hierarchical hand-over paths for TM oplev signals
  * To add setpoint of the TM oplevs before being sent to damping/DC control filters

=== Type B ===
==== Report for the week 16-12-2019 ====
 * Limit  switch for IM picomotors: last meeting there were concerns about the  pin 5 of the in-air cable being connected to shield and the case. The  solution would be to use an unshielded cable. See updated slides in this  [[https://www.dropbox.com/s/dh54u2hat9w8jzo/Limit_switch_IM.pdf?dl=0|link]].
 * SR2 neighborhood clean room survey.
  * I  didn't finish this week surveying the clean room. I realized I need  more information about the position of the handrails in the 2nd floor. I  will measure that on the 14th of January. If the analysis is required  earlier another person can take over. I left some files in Dropbox [[https://www.dropbox.com/sh/dsbdp5rrxt5sk5b/AABLaas7fA9dWnvAx40zYnR0a?dl=0|here]].
  * There's  not much space available to extend the clean room by a lot without  blocking valuable access into the +X arm. We will likely require to set  the oplev optics outside of the clean booth.
 * Type-B  and Type-Bp oplve survey: I went to the tunnel and took a look but, as  expected, important features are hidden under aluminium foil covers. I  will collect 3D CAD models for the main components.
 * I left a very humble TO DO list for commissioning [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/ToDo|here]].  I will do this when I come back depeding on the commissioning  priorities. Nevertheless, in case anyone wants to do it, please feel  free.
