=== 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. |
* Add more arc weights and tweak IP centering. * Replace two borrowed geophones. * Remove tape, writing etc on PI and PI items. * Add new feedthrough to lower part of tank (with Izumi-san-tachi). * Install cable for MIF pico on LBB (with Izumi-san-tachi). * Add ballast mass to LBB. * Install manual yaw adjuster. * Get top plate reduced? |

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.
- Install damping filters for SR2.
- Review DAC channel requests.
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Split SRx real-time models?
