[[../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)>> == ASAP == * Calibrate LEN OL * Ask commissioning team for window of opportunity. * Turn off TILT OL control. * Uncover breadboard. * Scan LEN QPD in horizontal and vertical while noting output. * Recenter LEN QPD. * Re-cover breadboard. * Re-engage TILT control. === Main Assembly Sequence === * Necessary for phase-I★★★ * --(Modify IP LVDT damping filters to include set point.)-- * --(TFs.)-- * '''''EXCHANGE YAW/VERT FRs at F0''''' * Check IP BIO is working or not. * Necessary for phase-II★★ * Calibrate IP LVDT actuation against IP LVDT sensing. (Klog 3553? http://klog.icrr.u-tokyo.ac.jp/osl/?r=3553) * Design PI Sensor blending filter. * Re-calibrate F0 GAS LVDT * Tune the LVDT sensitivity * Measure IP period; adjust ballast mass. * At some point (remotely)★ * Improve OL offloading. * Improve GAS offloading. * Spectral analysis of Oplev. * Design, install angular lock servo using OL. (Almost done for phase-I) * Adjust gains and debug damping for IM OSEMs and GAS LVDTs. (Almost done for phase-I) * Subtract DC level of Geophones. * Spectra analysis of PI sensors (PI LVDTs and Geophones). * Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs. * Set all EQ stops to TBD clearance. * Modify the model for IP coil driver control === Documentation and Operation Manual === * Add useful info from Enzo's notebook to BSData. <<Anchor(RealBSHang)>> == Tasks Not To Forget == === Major Tasks === * Move safety bars from BS AF area to SR2 area. * Close hole in floor above BS AF area. * 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. <<Anchor(elec)>> ==== Electrical ==== * Update BS Circuit diagram, D1503600 * Make generic for BS+SRx??? No, there are some differences. Still we need to summarize. * --(Note removal of LED/PD on TM OSEMs.)-- * Include information on assignment of channels to feedthrough positions. * Reflect gender-changers and non-flipping feedthrough adapters. * Reflect actual cable lengths. * Include LVDT pin size (1 mm). * Include Stepper pin size (1.6 mm). * Undo renumbering of IP items. * --(Page 10: "DIO Card # 0" should be "DIO Card # 1")-- * --(Include OutConfigBoards on OL page (Sheet 18).)-- ==== 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. |
