VIS Type B Near Term To-Do List
Issues to fix after BS Test Hang
Every Week
Facilities
- Vacuum and roll floor.
- Wipe ladders.
- Tidy tools, parts.
Longer Term
Design/Purchasing
- Do rough mass budget for SR2/SR3/SRM.
- Design SR assembly frame.
- Get another D-Sub breakout (Hirata).
- Design final SF ballast masses (Fabian).
- Finish/post assembly drawing for LBB and LBB damper ring (Hirata).
- Try rearranging arc weights to make room for magic wand (3D CAD or actual weights; Fabian or Hirata).
- If needed based on previous, order longer threaded rods for arc weights on PI (Hirata).
Real-time and SUMCON models
- 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.
BS Prism/Flag Gluing
- Locate new flags (Mitaka?).
- Locate mirror box (Mitaka).
- Locate prisms (Mitaka?).
- Arrange time with Hirose-san.
- Launder, pack clean suits etc for Kashiwa.
2017-06-19
Facilities
- Remove cling wrap from stuff.
- Plug stuff back in (charging station, KOACH filters, OL etc).
- Power up rack.
Main Assembly
- Unlock BF keystone and try running BF fishing rod to fix sag problem.
- Do up all EQ stops etc (except SF).
- Remove geophones.
- Crane suspension into tank.
- Hook LBB Cu ring.
- Hook LBB.
- Crane vacuum tank lid+ring black on.
- Remove vacuum tank lid (only).
Electronics
- Calibrate PI vertical LVDT.
- Set yoke on PI vertical LVDT (if necessary).
- Calibrate PI horizontal LVDTs.
- Remove port covers where feedthroughs will go, move feedthroughs from assembly frame and install on vacuum tank ring.
- Reconnect in-air cables.
Real-time and SUMCON models
- Derive and install PI LVDT matrices.
- Check LSOL section of k1visbs model.
