==== Report for the week of 4/1 ====
 * Support of Type Bp
  * Hirata-san procured the jigs for PRs and Takahashi-san tested one at TAMA.
  * Hirata-san cleaned up the flags for PR2 and Mark did the one for PRM.
  * Fabian helped Fujii-kun and Takashashi-san to reglue the flags.
 * Mark did a lot of maintenance on the MEDM screens:
  * Made the name of the suspension more obvious (no yellow text!).
  * Added rack temperature indicators.
  * Fixed the labels in the ADC screen (to reflect the LEN OL moving from ADC#0 to #1).
  * Fixed broken links.
  * Committed files to the SVN.
 * Mark did maintenance on the Guardian to make it give more helpful messages in the TRIGGER state. Formerly it only checked the user model watchdog and the coil driver watchdog, not the DACKILL, and gave the same generic notification for both. Now it checks all three and tells the user which need attention.
 * Mark tidied up the cables in the SR2 rack and returned a large pile of no-longer-used cables to the tent.
 * Mark started a !HealthCheck page on the Operation Manual wiki.
Fabian and Mark
==== Plan for week of 4/8 ====
 * Mark, Fabian at Kamioka Mon-Fri.
 * Help with Type Bp.
 * Health checks on Type B.
 * Monitor pumpdown.
==== Report for the week of 4/15 ====
 * Fabian debugged a dead stepper on SR3 (broken driver channel) and a dead geophone on SRM (unplugged cable). He made another update to the table used by the Python script for the stepper driver MEDM screen to reflect the remapping.
 * Fabian monitored the pumpdown and he and Hirata-san did post-pumpdown checks of all the suspensions. They were all healthy.
 * Hirata-san participated in the health checks and learned about the computer systems.
 * Mark did major revisions to the MEDM menu on the OVERVIEW screen with scripts for making `safe.snap` files and snapshots of setpoints. He made the `safe.snap` files in directories under `/opt/rtcds/kamioka/k1/target` into symbolic links to files in `/opt/rtcds/userapps/release/vis/k1/burtfiles`, alongside the setpoint files, so that they could be backed up to the SVN (as at LIGO).
 * Mark did major updates to his `vistools.py` Python package for manipulating the suspensions (based on his LIGO `sustools.py`). He added entries for Type B suspensions to the internal database and added commands for manipulating SET and DCCTRL blocks. He also added commands to simulate pressing on the `CLEAR HISTORY` and `LOAD COEFFICIENTS` buttons.
 * Mark started updating the `TYPEB.py` Guardian definition file to use `vistools.py`. So far only the `ENGAGING_IP_CONTROL` state has been fully rewritten and tested, but other states will be simple adaptations. It should be easy to do Type A and other Guardians in the same style.

==== Plan for week of 4/22 ====
 * Mark, Terrence at Kamioka Mon-Fri.
 * Fabian at Kamioka Mon-Thu.
 * Work with Lucia to do blending of the IP LVDTs and geophones.
 * More Guardian improvements.
  * Improve `vistools.py` (add more useful functions; add docstrings; add support for Type A/Bp/C; create test suite).
  * Finish and test new Guardian code using `vistools.py`.
  * Modify RT models and/or Guardian to revert to the SAFE state under control in all but the most extreme emergency situations (rather than suddenly shutting off all output).

Type B (Mark)

Report for the week of 4/15

  • Fabian debugged a dead stepper on SR3 (broken driver channel) and a dead geophone on SRM (unplugged cable). He made another update to the table used by the Python script for the stepper driver MEDM screen to reflect the remapping.
  • Fabian monitored the pumpdown and he and Hirata-san did post-pumpdown checks of all the suspensions. They were all healthy.
  • Hirata-san participated in the health checks and learned about the computer systems.
  • Mark did major revisions to the MEDM menu on the OVERVIEW screen with scripts for making safe.snap files and snapshots of setpoints. He made the safe.snap files in directories under /opt/rtcds/kamioka/k1/target into symbolic links to files in /opt/rtcds/userapps/release/vis/k1/burtfiles, alongside the setpoint files, so that they could be backed up to the SVN (as at LIGO).

  • Mark did major updates to his vistools.py Python package for manipulating the suspensions (based on his LIGO sustools.py). He added entries for Type B suspensions to the internal database and added commands for manipulating SET and DCCTRL blocks. He also added commands to simulate pressing on the CLEAR HISTORY and LOAD COEFFICIENTS buttons.

  • Mark started updating the TYPEB.py Guardian definition file to use vistools.py. So far only the ENGAGING_IP_CONTROL state has been fully rewritten and tested, but other states will be simple adaptations. It should be easy to do Type A and other Guardians in the same style.

Plan for week of 4/22

  • Mark, Terrence at Kamioka Mon-Fri.
  • Fabian at Kamioka Mon-Thu.
  • Work with Lucia to do blending of the IP LVDTs and geophones.

    • Improve vistools.py (add more useful functions; add docstrings; add support for Type A/Bp/C; create test suite).

    • Finish and test new Guardian code using vistools.py.

    • Modify RT models and/or Guardian to revert to the SAFE state under control in all but the most extreme emergency situations (rather than suddenly shutting off all output).
  • Work on Type B paper.
  • Tidy up.
    • Gather and clean tools.
    • Gather and organize unused parts and fasteners.
