==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Perry, Hirata-san): * We set things up again after the floor coating work. * We moved the PI into the second floor of the cleanbooth: * We cleared a path for the forklift (moving the portable cleanroom, worktable, power cables, vacuum pumps and other obstacles). * We got Saito-sensei to move the PI to the +Y side of the cleanbooth. * We washed and cling-wrapped a pallet. * We got Miyoki-san to disconnect the cables and curtain blocking the crane slot (and reconnect them afterwards). * We added some temporary crossbars in the top of the assembly frame and stored the SF cap on them to get it out of the way. * We craned in the pallet and set it up to bridge three floor joists. * We craned in the PI using Saito-san's adapter. * We couldn't find the original screws for the three PI transport plates so we substituted some others - fortunately there was no galling. * We had to connect the adapter to the crane with a sling because the ring for the hook was slightly too small). * We did a lot of cabling work: * We routed all the BF cables over the BF cap, up through the cable clamp on the SF-BF rod and up to the SF. (We had to redo a few because the Type 3 cable was at the flange end instead of the Type 1.) * We connected up the SF LVDT and FR stepper. * We started on rebalancing the BF (which had been perturbed by the weight and tension of all the cables). We got it rather better, but it needs more work. * We made another batch of anti-feedthrough adapters. |

Week of 4/10: * Hirata-san does scissor lift training 4/10. * Perry in Tokyo 4/10. * Debug/fix dead OSEM channel, TM-H4. * Debug BF/SF LVDTs. * Adjust BF pitch/roll. * Do TF from SF LVDT actuation. * Install temporary ballast mass in SF. * Lift SF/BF/... section and check total weight and SF balance. * Continue swap of PI LVDT connectors (female->male) * Start preparing LBB spring units. * Install pico drivers in rack, create MEDM interface (with Miyo-kun), and undo temporary connection of picos to old controller and joystick. Week of 4/17: * Crane in PI. * Connect SF/BF... section. * Temporarily remove PI and adjust SF ballast if necessary. |
* We finished tuning of BF No. 1. * We wired the LVDT, Picomotor and StepperMotor of BF No. 1. * We finished tuning of BF No. 7. * We wired the LVDT, Picomotor and StepperMotor of BF No. 7. * SF check (Hirata-san++). * We checked the load capacity with and without the cap. * We checked fit of caps. For the SF No. * Add cable clamps to bases. * Add cable clamps and Cu segments to caps (only if they fit well). * Cable LVDTs and steppers. * We finished the SR3 in-air cabling. ==== Plan for week of 4/2 ==== * Mark at Mitaka Mon, Kamioka from Tue. * Shoda-san at Mitaka * Others at Kamioka * -- * Glue SR3 (if available) * Build 2xIM, 2xIRM (if parts available - due 3/30) ==== Plan for week of 4/9 ==== * Shoda-san at Mitaka * Others at Kamioka * -- * Finish IMs and IRMs * Build 1xRM ==== Plan for week of 4/16 ==== * Start SR3 Hang? ==== Plan for week of 4/23 ==== * F0 blade prototype test ==== Plan for week of 4/30 ==== * Golden Week! ==== To-Do Lists, Schedule ==== * [[KAGRA/Subgroups/VIS/TypeB/March2018]] * [[KAGRA/Subgroups/VIS/TypeB/April2018]] * [[KAGRA/Subgroups/VIS/TypeB/ToDoBS]] * [[KAGRA/Subgroups/VIS/TypeB/ToDoSR]] * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=7779|JGW-L1807779-v1 Type B Schedule (SR)]] ==== Vacation Info ==== * Mark at LVC, then vacation, 3/18 (Sun) - 4/1 (Sun) * Fabian vacation, 3/26-4/27 (then gone). |
