Main Assembly Sequence
Realign OL.
- Cover OL with foil.
Offload IP P&Y offsets to picos.
- Diagonalize OL.
- Design, install angular lock servo using OL.
- Adjust gains and debug damping for IM OSEMs and GAS LVDTs.
Calibrate IP LVDT actuation against IP LVDT sensing.(Klog 3553? http://klog.icrr.u-tokyo.ac.jp/osl/?r=3553)
- Spectra analysis of PI sensors (PI LVDTs and Geophones).
- Design PI Sensor blending filter.
- Subtract DC level of Geophones.
- Modify IP LVDT damping filters to include set point.
- Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
- Set all EQ stops to TBD clearance.
- Measure IP period; adjust ballast mass.
- TFs.
Etc
- Move stuff out of PR2 area.
- Tidy/label parts.
- Move safety bars from BS AF area to SR2 area.
- Close hole in floor above BS AF area.
Software
- Update real-time model to number channels from #0.
- Do better interface to IP steppers (make a wrapper for Miyo-kun's driver which includes geometry matrix).
- Sort out SVN.
- Add support for comments to SUMCON.
- Create SUMCON model with values commented.
Medm screens
- Remove old OL stuff; add link to new OL stuff.
- Remove unused screens.
=== Documentation and Operation Manual===
- Publish matrices for IP FRs.
- Publish matrices for BS PI sensors v4.
- Finish Foton operation Manual.
- Complete MEDM operation Manual.
- Pico Motor operation Manual.
- Add useful info from Enzo's notebook to BSData.
Design
- Finalize redesign of IP yaw adjuster.
- Design better F0 FR adjuster.
- Design LBB ballast mass.
Tasks Not To Forget
Major Tasks
- Wipe any rust from around IP LVDTs.
- Update circuit diagram.
- (Time permitting) Try adding mass to IP.
- Update BS Install Procedure with screenshots from new on-assembly-frame 3D CAD.
- Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san).
- Figure out how to make PI yaw adjustment reliable.
Minor Tasks
Mechanical
- Put pointy-tipped screw in RM trolley for BS
- Return/replace borrowed parts:
- Temporary ballast mass (dog clamps) in BF.
Electrical
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.
