Archived To-Do Items

Issues to fix after BS Test Hang

Every Week

Facilities

  • Vacuum and roll floor.
  • Wipe ladders.

Longer Term

Design/Purchasing

  • Do rough mass budget for SR2/SR3/SRM.
  • Design SR assembly frame.
  • Get another D-Sub breakout (Hirata).

  • If needed based on previous, order longer threaded rods for arc weights on PI (Hirata).

Real-time and SUMCON models

  • Adjust OSEM ADC and DAC channel assignments to match cabling changes.

  • Check PI section of k1visbs model.

  • Make table of ADC/DAC assignments and check for consistency with D1503600 and k1visbs (Enzo, Mark)
  • Understand/document/debug Kokeyama-san's DIO stuff.
  • Measure LPCD and HPCD output filter response.
  • Design and install software compensation filters for LPCD and HPCD output filters.
  • Design and install GAS drift compensation filters.
  • Create a proper DAC Monitor MEDM screen.
  • Improve ADC Monitor MEDM screen.
