| * Type B Past Week Summary * Mark did a Type B schedule presentation at the Extended Chiefs Meeting. 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 has offered to re-grease 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. * 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. * 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. * 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) * Apply vacuum grease to jacks for BS assembly frame (Takahashi) * 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 B (Mark) === ==== Report for week of 4/2 ==== * We received the SR3 but found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK). * We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday. * Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws. * Fujii-kun, Enzo and team finished the preparation, adjustment and calibration of the SFs and BFs. * Fujii-kun and Yamamoto-kun got the SR3 real time model running. * Enzo finished setting up the SR3 and SRM racks. (The SRM rack still lacks a front-end, and power and network connections, but the SR3 is now ready for testing.) * Shoda-san worked on getting quotes for the ballast masses, on design of the SRM metal mass, and on splitting the BS model to reduce the load on the front-end computer. ==== Plan for week of 4/9 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka * Tanioka-san at Mitaka? * Others at Kamioka * -- * Finish IMs and IRMs * Glue SR3 mirror ==== Plan for week of 4/16 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka * Tanioka-san at Mitaka? * Others at Kamioka * -- * Build 1xRM * Start SR3 Hang * Align assembly frame. ==== Plan for week of 4/23 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka? * Mark, Enzo at Kamioka * Hirata-san at Mitaka * Tanioka-san at Mitaka? * -- * Clean parts (cable clamp bases, etc, etc). * Observe KAGRA Phase 1 operations, assist if problems arise. ==== 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). |

Type B (Mark)
Report for week of 4/2
- We received the SR3 but found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK).
- We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday.
- Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws.
- Fujii-kun, Enzo and team finished the preparation, adjustment and calibration of the SFs and BFs.
- Fujii-kun and Yamamoto-kun got the SR3 real time model running.
- Enzo finished setting up the SR3 and SRM racks. (The SRM rack still lacks a front-end, and power and network connections, but the SR3 is now ready for testing.)
- Shoda-san worked on getting quotes for the ballast masses, on design of the SRM metal mass, and on splitting the BS model to reduce the load on the front-end computer.
