Real BS Hang Tasks
Major Tasks
- Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san).
- Get pico drive screens fixed (Miyo-kun)
- Final ballast mass production for BF and SF (Hirata-san). (have quotes)
- Design of receptacles for rods with 8 mm heads.
- Possible rebuild of BF and/or SF
- Set up build/test stand for filters.
- Get filter test weights.
- Find spare BF blade(s).
- Reclean stuff:
- PI (remove Kapton tape etc, etc).
- LLB damper stuff, especially Cu segments.
- Calibrate PI vertical LVDT.
- Set yoke on PI vertical LVDT (if necessary).
- Calibrate PI horizontal LVDTs.
Minor Tasks
Mechanical
- Get clean bag laundered.
- Put pointy-tipped screw in RM trolley for BS
Swap out temporary ballast mass in BF, SF.
- Return/replace borrowed parts:
- Lock washers for LBB dampers
- Temporary ballast mass (dog clamps) in BF.
- Wide-mouth OSEMs from RM to Akutsu-san
Adjust height of crossbars below BF.
If possible, fix galled pole in BF level of EQ stop.
- Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.
Check inside SF for lost ruler.
- Tighten PI yaw return spring.
- Get Cu O-rings for feedthroughs.
Electrical
- Decide final in-vacuum and in-air cable routing (Enzo).
- Calibrate all LVDTs (Enzo, Mark).
- Remove cling wrap in BF and install vacuum-compatible heat shrink.
- Remove cling wrap on connections for PI vertical stepper and install vacuum-compatible heat shrink (needs wider diameter heat shrink or smaller pins).
- Rewire PI horizontal steppers with vacuum-compatible cable.
- Adjust yoke on BF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height).
Real-time and SUMCON models
- Create SUMCON models for full BS and major installation milestones.
Create controls design description (cf LIGO-T1100378).
- 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.
SR Prep Tasks
Design/Purchasing
- Do rough mass budget for SR2/SR3/SRM.
- Design SR assembly frame.
- Design final SF ballast masses (Fabian).
