Adjust with jacks. * Unlock IP and adjust to center with jacks. * Adjust pitch/yaw/vertical of dummy optic. * Start TFs. === Electronics === * Get pico drive screens fixed (Miyo-kun) * Order final OSEM cables (six of 1.7 m, two of 2.2 m, two of 2.4 m; Sato-san). * --(Disconnect in-vacuum and in-air cabling from feedthroughs (label in-vacuum ones).)-- * Remove port covers where feedthroughs will go, move feedthroughs from assembly frame and install on vacuum tank ring. * Reconnect in-vacuum cabling. * Adjust in-air cabling to match 135° rotation of BS. * Reconnect in-air cables. * Calibrate PI vertical LVDT. * Set yoke on PI vertical LVDT (if necessary). * Calibrate PI horizontal LVDTs. === LSOL === * Assist Simon with hardware installation of LSOL (week of 6/26?). * Assist Simon with modifications to realtime model for LSOL (week of 6/26?). === Real-time and SUMCON models === * Derive and install PI LVDT matrices. * Check LSOL section of k1visbs model. <<Anchor(RealBSHang)>> == Real BS Hang Tasks == === Major Tasks === * Final ballast mass design/production for BF and SF (Fabian, Hirata-san). * Get final OSEM cables (six of 1.7 m, two of 2.2 m, two of 2.4 m; Sato-san). * Possible rebuild of BF and/or SF * Set up build/test stand for filters. * Get filter test weights. * Find spare BF blade(s). * Prepare real BS: * Coordinate with Hirose-san. * Book transport of mirror (Kashiwa to KAGRA) * Gather mirror box, gluing supplies, prisms, magnets, new flags, new flag jigs. * Solve problem of lack of scribe line on one side of BS (Mark, Hirata-san). * Organize cleanroom gear for Kashiwa trip(s). * Put magnets in flags. * Glue flags/prisms at Kashiwa. * Reclean stuff: * PI (remove Kapton tape etc, etc). * LLB damper stuff, especially Cu segments. * Try rearranging arc weights to make room for magic wand (3D CAD or actual weights; Fabian or Hirata). * If needed based on previous, order longer threaded rods for arc weights on PI (Hirata). === Minor Tasks === ==== Mechanical ==== * Get clean bag laundered. * 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). |
