| ==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * We improvised a solution for ballast mass on the BF, using some heavy dog clamps meant for pedestals, washed and wrapped in foil. We we use them for the duration of the BS Test Hang and then swap them out for custom masses. * We put back the original BF jacks (replacing the cantilevered jacks that had been borrowed from the SF level to allow access to the BF blade screws). * We rearranged the BS rack, closing the gaps between boxes (per request of Miyakawa-san. We also renumbered some boxes, connectors and cables so as to use zero-based numbering (#0, #1, #2,...) throughout. * We routed the OSEM cables into the external cable rack (rather than through the PR2 area). * We connected up the BF LVDT, and BF fishing rod stepper motor. * We installed a signal generator for the LVDT. * We connected the super motor driver box to the Internet and attempted to set it up, but with no success so far. * We found the final picomotor driver (we have been using the one from TAMA in the clean booth). * We found many items that we will need soon, including the copper ring for the SF. * We found issues with the digital system (the computer driving the rack had been changed from k1pr2 to k1bs, which causes problems) and worked with DGS to fix them. It now mostly works but the real-time model crashes from time to time. ==== Plan for coming weeks ==== Next week: * Everyone (Mark, Fabian, Enzo, Hirata-san) at Kamioka, Monday-Thursday. * Work on electronics, possibly suspend and weigh BF. Week after next: * Everyone (Mark, Fabian, Enzo, Hirata-san) at Kamioka, Monday-Friday. * Add SF and suspend BF. |
==== Report for week of 3/19 ==== * Fujii-kun successfully assembled and tested a geophone pod (klogs 4492, 4508). ==== Plan for week of 3/26 ==== * Tanioka-kun joins. * Mark vacation. * Shoda-san at Mitaka * Others at Kamioka * -- * Lay SR3 in-air cabling (Enzo++). * Finish tuning of BFs (Hirata-san++). * SF check (Hirata-san++). * Check load capacity. * Check fit of caps. * Add cable clamps to bases. * Add cable clamps and Cu segments to caps (only if they fit well). * Cable LVDTs and steppers. ==== Plan for week of 4/2 ==== * Glue SR3 (if available) * Build 2xIM, 2xIRM (if parts available - due 3/30) ==== Plan for week of 4/9 ==== * 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). |
