It was decided to order a second assembly frame so that the BS/SR2/SR3/SRM installations can overlap more. * Mark and Hirata-san helped Mirapro construct the assembly frame ([[https://goo.gl/photos/tVGoebw7FTRMAYB2A|photos]]). * Mark and Hirata-san took the jacks and adapter plates off the frame, and cleaned them to remove as much of the original grease as possible. Takahashi-san re-greased them with vacuum grease. * Mark and Hirata-san wiped down the assembly frame and put the clean bag on it. * Saito-san, Ohishi-san and several people from Mirapro adjusted the position of the BS chamber. * Mark plugged the geophones back into the PR2 rack and checked that the repaired cable was working. * Fabian did more pre-assembly of the RM/IM/IRM. * Fabian designed modifications for the brackets on the security structure for immobilizing the IM, and Hirata-san did 2D drawings from them. * Takahashi-san ordered 10 mm diameter x 10 mm long magnets for the IM flags. * Mark inspected the SR2 section of the clean booth to see where SR2 assembly could be done. The slot in the ceiling for the crane runs in the ±X direction (at right angles to that for the BS), and there are suitable space on both the +X and the -X sides of the SR2 tank. * Hasegawa-san (of Hirose-san's lab) took delivery of the cup for removing the prisms on the dummy BS. It fits well. * Tatsumi-san ordered [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5357|modifications]] to the BS gluing jig to make it easier to remove the pieces holding the flags after the flags are attached. The parts are expected Fri 7/8. He also ordered more EP30, but this won't arrive until the week of 7/18. * Hirata-san measured another filter and cleaned parts for Fabian * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test ongoing. * We will produce two new RMs. So we do not need to modify the existing ones. * We need to schedule the production of the new RMs with ATC * Lower breadboard stuff * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss. * Breadboard springs (in manufacture, expected end of July) * Nail-head parts - RECEIVED. * Documents * BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] * To-do list during Mark's vacation * Apply grease to jacks for assembly frame (Takahashi) * Finish assembly of BS IM, RM and IRM (Fabian). * Weigh IM/RM/IRM (Fabian, Hirata) * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian). * Analyze geophone data (Mark, Shoda) * Remove glue from dummy BS face (Fabian) * Remove prism from dummy BS (Hirose, Fabian?) * Reglue flags and prisms (Tatsumi, Fabian) * Buy wire for BS and RM (Hirata) * Clean wire for BS and RM (Hirata) * Do fit/function test of winches (Fabian/Hirata) * Ship winches to Kamioka (Hirata/Fabian) * Work on BS simulation (Fabian) * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) * Write more of payload assembly procedure (Fabian) * Write more of main assembly procedure (Mark) * Longer term to-do list * Do BS Simulink model (Mark, Kokeyama) * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs. * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) * Check SR RM machining test progress (Hirata) === Type-Bp (Shoda) === * Type-Bp modification 3D Drawings * Saito-san implemented the Virgo design into the Type-Bp design. (I asked him a little more updates.) * We have some questions about F7 LVDTs. * Coil specification * Its design (Slits on the coils. The place where the wires suppose to come out.) * '''Next meeting will be on July 14th from 4PM (meeting arrangement: Raffaele)''' * '''[A/I] Structual analysis''' * Installation related issue * Technical document is written by Shoda. * Does the Type-B team use the hanging frame for iKAGRA PR2? * '''[A/I] Shoda will decide the meeting date will Mirapro.''' === IMMT (Ohishi) === * Schedule * Finally succeeded in installing Windows and Microsoft Project. * '''Make a schedule by Wednesday next week''' * Asking a company to make a quotation for writing 3D CAD drawing of IMMT suspensions from 2D parts plans. * BS chamber was relocated (6th and 7th July). * Measurement with tape measure shows that now the chamber center is (x, y) = (0mm, +2mm) based on the floor points. * Rotation: CCW 0.15deg. === Watchdog system (Tanaka) === * Changes the scale of the vertical axis(for PhotoMos Relay).[[http://gwdoc.icrr.u-tokyo.ac.jp/DocDB/0053/E1605344/003/Project%20WDS%20Experiment_20160701-V2.pdf|PDF]] === Safety === * Nothing == Discussion == * Inertial Sensors for Type-B (Mark, Fujii) * '''Take time series data of Geophone output remotely on Monday (Fabian)''' * '''Find old calibration factors for Geophones (Fabian)''' * '''Make the three-sensor correlation calculation to deduce the sensor noise (Fabain with Shoda)''' * '''Fabian will update the status to Aso on July 13th''' * What to do with the SR preparation * Hirata-san needs to stay in Mitaka for the preparation of the SR suspensions as well as the SFs and BFs for Type-A. * '''Aso will consult with SEO to find one or two students who can stay long in Kamioka and help Mark and Fabian in the test hanging of BS.''' == Site work plan for the next week == * Mon: Takahshi (witness/supervise the installation of a cross-tube) * Tue: * Wed: * Thu: * Fri: == Travel Plans == * Travel (Week of 7/11): * Takahashi:11 (Cross tube installation) * Shoda: * Mark: * Fabian: * Okutomi: * Fujii: * Ishizaki: * Hirata: * Sato: * Ohishi: * Travel (Week of 7/18): * Takahashi: * Shoda: * Mark: * Fabian: * Okutomi: * Fujii: * Ishizaki: * Hirata: * Sato: * Ohishi: Mark is away: July 8-20 Visit by ATC on July 20 == Next meeting == 2016/7/15(Fri) 13:30 - (Takahashi-san will be the chair)
