Coming Weeks
2018-11-05
SRM (top priority)
- Etc
Solder more cables.
Ultrasonically clean more cables.
Work out optimum LPCD output resistance; get one box modified.
- Work out how to change LPCD watchdog threshold; get one box modified.
- LBB
Lay out LBB damper ring pieces near tank.
- Put magnets on LBB magnet ring.
- Move KOACH filters
- Put LBB damper rings in tank.
- Set tank jacks to nominal height.
- Main sequence
Run DC power and network to SRM_IP stepper driver.
Add all steppers and picos to driver list and MEDM screens.
Prepare SF magnet ring.
Install #353 poles
Move NB-03 jacks down; disassemble top of AF.
Crane PI into AF.
Install F0-SF rod (#331) and flying saucer.
Route SF/... cables up to underside of F0.
Install weaker CuBe spring.
Add SF trim mass to leave 1.2 kg margin.
Tweak BF trim mass to compensate for new cables.
Measure bounce frequencies.
- Do vertical height budget.
SR2 (low priority)
Unclamp LBB ring sandwich.
Set LBB receptacles to CAD positions.
Remove spacers; get LBB hanging.
- Set up OL.
2018-11-12
SRM
- Main sequence
- Cable/test IP LVDTs.
- Cable/test IP FRs.
- Unlock IP and center roughly.
- Calibrate IP LVDTs.
- Check/adjust alignment of SS.
- Add arc weights and geophones (or extra mass equivalent to geophones).
- Cable/test geophones.
- Improve centering/tuning of IP and SS alignment.
SR Prep Tasks - To Be Scheduled
Tunnel
- Check which LVDT cards are in which boxes.
- Get at least one BIO Converter chassis fully connected (CONTEC BIO card, WD and stepper motor chassis) for implementation and test of stepper motor reset function.
- Install, cable PI yaw steppers.
- Correct flipped connections in SRM PI LVDTs.
- Check SR2, SR3 TM coil gains for magnet polarity compensation.
- Replace chipped magnets (12x12x12 mm) in SR3 IP, H1 and H2.
Mitaka or remotely
- Write generic Type B Guardian; make BS and SR3 inherit from it; make analog WD optional for now (all suspensions will get them eventually).
- Create software stepper drivers for SR3 and SRM and link to them from STEP_MASTER.adl screen.
- Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
- (Continue to) soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Review DAC channel requests.
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Split SRx real-time models?
