[[../ToDoSR|SR To-Do Items]] [[#EveryWeek |Every Week]] [[#ComingWeeks |Coming Weeks]] <<Anchor(EveryWeek)>> == Every Week == === Facilities === * Vacuum and roll floor. * Wipe ladders. * Tidy tools, parts. * Get stuff from [[../WishList]] <<Anchor(ComingWeeks)>> == 2017-10-30 == === 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. <<Anchor(RealBSHang)>> == 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 [[https://dcc.ligo.org/LIGO-T1100378/public|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. |
