=== 2019/7/16(Tue.) ===

==== Schedule ====
 * ~7/31: Trial for DRMI with polarization.
 * 7/6~: Trial for mass lock

 * ITMX

 * ETMX

 * ITMY
  * 7/4: Turbo pump on

 * ETMY
  * 7/4: Turbo pump on


 * Long term:
  * --(4/22-5/31: Yarm commissioning)--
  * --(5/27-6/30: DRMI commissioning)--
  * 7/1-8/9: FPMI/DRFPMI commissioning
  * 8/12-10/4: ASC
  * 10/7-11/15: Post Commissioning
  * 11/18-12/13: Noise hunting


==== Note ====


==== Night work ====

==== Weekend ====

==== Report of work ====
 * OMC: Beam spot on mirror moved. One (or more) of the mirrors seems to be misaligned. OMC will be pulled tomorrow.
 * Y arm: 20dB suppression on LSC below 1Hz was seen on mass lock trial.
  * Opleve control was slightly changed from IM control to TM control.
  * High frequency is limited by noise. Needs high power coil driver modification.
 * Type B: H2 on SR3 was noisy, but needs more time to investigate it.
 * 80mHz peak was reduced by changing damping setting.
 * RTPC for ASC and ALS were dead somehow.


==== Work plan ====


----
== Today's work plan: 2019/7/16 1PM - 2019/7/17 1PM ==

Commissioning leader: Miyakawa (July 16th),  Aso (July 17th)

=== Afternoon ===
 * ETMY !L2Angle decoupling (Yamada, Nakano)
 * Check the schematic of the High Power Coil Driver (Fabian, Terrence)
 * Fix the CARM board boost issue (Enomoto)
 * Design a filter for DARM (Stefan)

=== Evening ===
 * Y-arm mass lock trial (SB, EY, MN, et al)

=== Morning ===
 * DGS maintenance 
  * Power supply replacement of SR3 (Yamamoto)
 * ITM T-cam computer replacement (Yokozawa)
 * OMC extraction (Aso, et al)
 * Check dimensions around OSTM (Takahashi)

----
== Standing issues ==

 * Y-arm lock
  * ETMY suspension control
   * !L2Angle decoupling
   * ETMY coil driver range increase
  * CARM board boost does not engage
 * DRMI lock stability
  * Model HOM-PHD signal distortion (Aso, Kokeyama)
  * Search for better Gouy phase in PRC
 * Initial alignment automation
 * Type-A related
  * Add aligned state in Guardian (Kokeyama)
 * Type-B related
  * SR3 Yaw motion is too large
   * Different ground level between the IO chasis and the AA filter box may be the reason
   * Replace the DC power supply
  * BS IM2TM transfer function measurement
 * Type-C related
  * Check dimensions around the OSTM
  * OSEM characterization for OSTM
 * OMC
  * Extract OMC
  * Check the OMC on the AS table
 * Laser safety
  * Debug the laser safety guardian
