| * Activity report for week of 12/19 * Mark and Fabian checked Hirata-san's drawings and parts/fastener lists for the SRM/PRM order and various other drawings. [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5964| D1605964]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5965| D1605965]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5956| D1605956]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5963| D1605963]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5977|D1605977]], etc. * Fabian designed a simple two-piece hold-down device to immobilize the SRx IMs during the optic and RM hanging. It avoids having to remachine all the IM support bars to allow for hold-down screws. The Type Bp team might also want to use it. * Aso-san and Mark discussed the [[KAGRA/Subgroups/VIS/VISMinutes20161216#BFIssue|BF issue]] from last week. * It was decided to ask Takahashi-san to take a look at the BF while he's at Kamioka this week. * It was decided to have the BS bottom filter moved to Mitaka for tuneup and adjustment as soon as possible in the new year. * Raffaele, Aso-san, Mark and Fabian discussed having much smaller/shorter BS and SR stub flags plus longer, coil-only OSEMs. * Aso-san volunteered to do the OSEM design. * Hirata-san made Pack'n'Go archives of the existing designs as a baseline for Aso-san. * Hirata-san searched for missing PR mirror box parts. * Miyakawa-san finished recabling the PR2 rack and got the real-time model running again. The model still needs lots of work, but it has the OSEM functionality needed for the next test-hang stage, plus Okutomi-san's improvements. |
* Hirata-san: * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank). * Liaised with IJECT. * Made an inventory for Type B (BS and SR). * Packed and shipped second winch to Kamioka. * Packed some jigs for adjusting BF blades. * Attended NINS information security seminar. * Attended the public hearing for the Opt-IR Research Division Chief Election. * Mark and Fabian at Kamioka (plus Enzo for 2 days): * Finished rebalance of IM * Reinstalled IRM, adjusted OSEMs * Replaced broken Type 3 cable on IM-H1 OSEM. * Fixed issues with k1visbs real-time model. * Started TFs from IRM OSEMs to IRM and IM OSEMs. * Mark, Fabian and Enzo * |
