(Mark) * Glue flags/prisms. === Electronics === * Document LVDT driver rebuild and other changes. * --(Fix #0 LVDT actuator coil.)-- * Get pico drive screens fixed (Miyo-kun) === Main Assembly === * Do TFs. * Experiment with rearranging arc weights to accommodate magic wand. * Remove arc weights; load onto LBB; measure total load capacity. * Unload arc weights and store. * Dismantle LBB and rings. * Remove screw feet. * Replace blocks. * Unhook. * Reinstall spacers and clamps on LBB damper rings. * Unhook rods supporting LBB intermediate ring. <<Anchor(RealBSHang)>> == Real BS Hang Tasks == === Major Tasks === * Final ballast mass production for BF and SF (Hirata-san). (have quotes) * Design of receptacles for rods with 8 mm heads. * --(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). * 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). |
