| * Activity report for week of 12/19 * Hirata-san made (and Fabian and Mark checked) drawings and parts/fastener lists for the SRM/PRM order and various others: [[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 BS real-time model running again. (The problem had been a new requirement for a safe.snap file imposed by RCG2.9.7.) 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: * Made cables for LVDT. * Made drawings for new wire clamps. * Asked ATC for manufacturing parts.(and modified drawings.) * Asked quotes for SDC coating for hooks. * Sent packing tools for BF. * Talked with i-ject about quotes for payload. * 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. |
