| ==== 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). * 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. |
==== Report for Golden Week ==== * Mark monitored vent and pumpdown, and worked on vistools.py. |

| ==== 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. |
==== Report for the week of 5/6 ==== * Lucia and Terrence got the blending working for the IP LVDTs and geophones. * Terrence and Mark modified the models and MEDM screens to add a new IP block, IDAMP, for damping using the blended signal with inertial information, and a new DAMPMODE block for ramping smoothly between IDAMP and the old DAMP. * Mark worked on vistools.py, improving the support for cdsMuxMatrix blocks (e.g., OSEM2EUL) and adding support for cdsRampMuxMatrix blocks (e.g., the newly introduced DAMPMODE). He also created two sets of unit tests, unittest.py and unittest.sh, for the two modes of use (as a Python module in other Python programs, and as a command-line utility in bash). ==== Report for week of 5/13 ==== * |
