| [[#EveryWeek |Every Week]] [[#ComingWeeks |Coming Weeks]] [[#RealBSHang|Preparation for Real BS Hang]] [[#SRPrepTasks|Preparation for SR Installation]] <<Anchor(EveryWeek)>> == Every Week == === Facilities === * Vacuum and roll floor. * Wipe ladders. * Tidy tools, parts. * Get stuff from [[../WishList]] <<Anchor(ComingWeeks)>> == 2017-07-31 == === Facilities === * Re-secure floor panels around tank. * Wipe entire frame; blow dust out of grooves. * Organize new OL for setting BS pitch (Fabian). === Design/Documentation/Planning === * Do version of 3D CAD with final-hang arrangement of suspension and LBB damper stuff (Hirata-san). === Electronics === === Main Assembly === * Remove dummy BS from RM. * Install coil-only OSEMs. * Measure coil resistances of wide-mouth OSEMs, new coil-only OSEMS (for Michimura-san). * Look up log book to find serial numbers of old coil+sensor RM OSEMs. * 2016-09-07: H1 = #22, H2 = #23, H3 = #25, H4 = #26 * Pack RM coil+sensor OSEMs, label them with original serial numbers, and return them to Akutsu-san. * Remove IM end panel and check centering of IM picos. * Reassemble top of AF. * Check verticality of AF, height of crossbars, centering of optical table. * Move NB-03 jacks at PI level of AF to top level. * Set height, level of IM support screws. * Install IM. === Time permitting === * Remove LBB rings. * Send rings for recleaning. <<Anchor(RealBSHang)>> == Real BS Hang Tasks == === Major Tasks === * Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san). * LBB ballast mass. * Research real payload. * Do improved mass budget. * Get pico drive screens fixed (Miyo-kun) * Final ballast mass production for BF and SF (Hirata-san). (have quotes) * Design of receptacles for rods with 8 mm heads. * Possible rebuild of BF and/or SF * Set up build/test stand for filters. * Get filter test weights. * Find spare BF blade(s). * Reclean stuff: * PI (remove Kapton tape etc, etc). * LLB damper stuff, especially Cu segments. * Calibrate PI vertical LVDT. * Set yoke on PI vertical LVDT (if necessary). * Calibrate PI horizontal LVDTs. * Unlock BF keystone and try running BF fishing rod to fix sag problem. === Minor Tasks === ==== Mechanical ==== * Get clean bag laundered. * Put pointy-tipped screw in RM trolley for BS * Swap out temporary ballast mass in BF, SF. * Return/replace borrowed parts: * Lock washers for LBB dampers * Temporary ballast mass (dog clamps) in BF. * Wide-mouth OSEMs from RM to Akutsu-san * Adjust height of crossbars below BF. * If possible, fix galled pole in BF level of EQ stop. * Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match. * Check inside SF for lost ruler. * Tighten PI yaw return spring. * Get Cu O-rings for feedthroughs. ==== Electrical ==== * Decide final in-vacuum and in-air cable routing (Enzo). * Calibrate all LVDTs (Enzo, Mark). * Remove cling wrap in BF and install vacuum-compatible heat shrink. * Remove cling wrap on connections for PI vertical stepper and install vacuum-compatible heat shrink (needs wider diameter heat shrink or smaller pins). * Rewire PI horizontal steppers with vacuum-compatible cable. * Adjust yoke on BF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height). ==== 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. * Create a proper DAC Monitor MEDM screen. * Improve ADC Monitor MEDM screen. <<Anchor(SRPrepTasks)>> == SR Prep Tasks == === Design/Purchasing === * Do rough mass budget for SR2/SR3/SRM. * Design SR assembly frame. * Design final SF ballast masses (Fabian). === Electronics === * Get cables/cards for SR3: * 5 DSub-37 cables (tent) * 5 DSub-15M to DSub-9M adapter cables (tent) * 3 DIO cards (tent) * 2 DSub-9 FF gender benders (for LVDTs) * extra ADC card(s)? * extra DAC card(s)? * BNC-LEMO adapter (for LVDTs) * etc |
