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.
  • 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.
