| * Type B Past Week Summary * Mark, Fabian and Hirata-san cleaned glue off the dummy BS, attached Akutsu-san's new SS mirror plates, reglued the flags and prisms, and removed the gluing hardware, so the dummy BS is ready for shipping. Tatsumi-san's refinements to the tooling (especially the new flag holders) worked very smoothly. We were more generous with the glue and much more careful with the alignment of the prisms to the barrel, both during rehearsal and the final gluing. * Mark wrote up the gluing procedure as a new document [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5505| E1605505]]. (The original plan was to do an addendum to Tatsumi-san's PR gluing procedure JGW-E1504248, but there was too much material.) * Hirata-san organized with Takahashi-san to get the BS payload masses shipped to Kamioka. They will go in an air-ride truck on Wed 8/17 together with a load of Type A stuff, and will arrive early on Thu 8/17. * Hirata-san measured another standard filter. * Fabian worked on the payload assembly procedure. * Komori-kun, Kuwahara-kun and Akutsu-san calibrated an initial batch of 7 wide-mouthed OSEMs. They will be shipped to Kamioka on Friday. * Type B ongoing issues * OSEMs * First batch of 7 ready for shipping. * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * Lower breadboard stuff * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss. * 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 * Weigh IM/RM/IRM (Fabian, Hirata) - DONE * New trim mass - ORDERED. * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - READY TO SHIP. * Analyze geophone data (Fabian/Shoda) - DONE. * Remove glue from dummy BS face (Fabian) - DONE. * Reglue flags and prisms (Tatsumi, Fabian) - DONE. * Clean wire for BS and RM (Hirata) - DONE * Get new winch parts for new wire diameters - ORDERED, expected 8/5. * Do fit/function test of winches (Fabian/Hirata) - fit test DONE, function test from 8/8 * Ship winches to Kamioka (Hirata/Fabian) * Work on BS simulation (Fabian) * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - ONGOING. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of main assembly procedure (Mark) - ONGOING * 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) |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Enzo, Yoshioka-kun): * We experimented with rearranging the arc weights to accommodate the magic wands and came up with a suitable scheme. * We used spare arc weights as extra ballast on the LBB to get it to float, and measured the height for a known load. * We put the blocks back under the LBB and unhooked it. * We moved the suspension from the tank back to the assembly frame. * We craned the LBB rings down onto the LBB but did not remove them yet. (This however is the last crane work in the tank until reinstallation, so the lid does not have to come off again and the pallet can be used for the PI.) * We put the crossbars back in the assembly frame underneath the SF and BF (and corrected an error in the height of the BF ones). * We checked the centering of the security frame in the assembly frame and disconnected it from the PI. One M12x35 screw galled after a few turns and will need attention. * Enzo started setting up the SR3 rack (with help from Yamamoto-san). * We received the real BS optic and gluing tools, and glued the disks and rods into the modified magnet jigs. We also tried the re-made secondary prisms in the gluing jigs and made shims to hold them more securely. At Mitaka (Fabian and Hirata-san): * Hirata-san shipped the optic and gluing tools to Kamioka. * Hirata-san did drawings and RFQs for IM/BF/SF ballast masses * Fabian worked on the SRx assembly frame. ==== Plan for week of 7/18 ==== Full team at Kamioka from Tue-Fri, except Hirata-san (Tue-Wed only). * Glue prisms/magnets on BS. * Dismantle suspension. * Finish setting up filter service area (mostly already done by Mirapro). * Move BF to filter service area, start rebuild. ==== Plan for week of 7/24 ==== Full team at Kamioka from Mon-Fri, except Hirata-san (Tue-Fri) and Enzo (vacation). * Finish BF rebuild. * Recheck alignment of assembly frame and centering of optical table. * Install IM, suspend BS and RM.

Type B (Mark)
Past week report
At Kamioka (Mark, Enzo, Yoshioka-kun):
- We experimented with rearranging the arc weights to accommodate the magic wands and came up with a suitable scheme.
- We used spare arc weights as extra ballast on the LBB to get it to float, and measured the height for a known load.
- We put the blocks back under the LBB and unhooked it.
- We moved the suspension from the tank back to the assembly frame.
- We craned the LBB rings down onto the LBB but did not remove them yet. (This however is the last crane work in the tank until reinstallation, so the lid does not have to come off again and the pallet can be used for the PI.)
- We put the crossbars back in the assembly frame underneath the SF and BF (and corrected an error in the height of the BF ones).
- We checked the centering of the security frame in the assembly frame and disconnected it from the PI. One M12x35 screw galled after a few turns and will need attention.
- Enzo started setting up the SR3 rack (with help from Yamamoto-san).
- We received the real BS optic and gluing tools, and glued the disks and rods into the modified magnet jigs. We also tried the re-made secondary prisms in the gluing jigs and made shims to hold them more securely.
At Mitaka (Fabian and Hirata-san):
- Hirata-san shipped the optic and gluing tools to Kamioka.
- Hirata-san did drawings and RFQs for IM/BF/SF ballast masses
- Fabian worked on the SRx assembly frame.

- Move BF to filter service area, start rebuild.
Plan for week of 7/24
Full team at Kamioka from Mon-Fri, except Hirata-san (Tue-Fri) and Enzo (vacation).
