Type B (Mark)
Report for the week of 4/8
- Support of Type Bp
- Mark made lots of Guardian improvements:
- Used Guardian's timer functionality to drastically reduce the number of notifications during ramping.
- Added new requestable states DCCTRL_ONLY and NEUTRAL (and associated transitional states) to facilitate testing.
- Tidied up the code to use tabs consistently throughout for indentation.
- Disabled the test for the IM-H coil driver WD (to work around the fact that only the relay in the chassis has been disabled, not the WD signals going to the BIO).
- Mark made lots of Guardian improvements:
- We opened the BS tank lid and offloaded a large IM-Y offset to F0-Y with manual adjustment of the broken yaw mechanism).
- We opened the SR2 side doors and adjusted the V1 OSEM to mid-range.
- Mark offloaded a large SR2 IM-Y offset to F0-Y.
- Mark did health checks for BS, SR2 and SR3.
- Fabian offloaded yaw from SRM and did the SRM health check.
- Fabian updated the Python code for the stepper driver MEDM screen to reflect that two stepper drivers have different mappings to work around dead channels.
- Fabian monitored pumpdown on Friday afternoon and will continue on Saturday.
Plan for week of 4/15
- Mark, Hirata-san at Kamioka Tue-Thu.
- Fabian at Kamioka Mon-Wed.
- All at f2f Meeting 4/19-21.
- Post-pumpdown health checks.
- Teach Hirata-san about the computer systems and control theory.
- Work with Lucia to do blending of the IP LVDTs and geophones.
- More Guardian improvements.
- Update vistools.py (formerly LIGO sustools.py) for Type B and KAGRA, and have the TYPEB.py Guardian use it where appropriate.
- 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.
