| ==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * With help from Kokeyama-san and Miyakawa-san, we debugged a problem with the real-time model freezing, which turned out to be the IO chassis shutting down because of brownout condition from an overloaded AC circuit. A combination of extra boxes added to the rack, plus surge current from the air shower could draw the full 20 A limit of the circuit. Awai-san ran a cable to a separate circuit and we moved the IO chassis onto that. * We got the stepper motor cabling and driver working, and tested the BF fishing rod stepper motor. * We got the LVDT cabling, driver and associated parts of the real-time model working. * We found all the parts for the SF and the SF section of the security structure, and prepared the SF. However we then removed the Cu ring from the top cap for recleaning. * ==== 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 3/26 ==== * 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). |
