| * Type B Past Week Summary * Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa. * The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka. * Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa. * Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror. * Fabian designed an extra 600 g of trim masses for the IM and Hirata-san made drawings and ordered them. The design allows for the masses to be added to the IM even after it has been placed in the assembly frame and the dummy optic and RM have been hung, so it should not delay work. * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; another few were assembled and a batch of 7 were washed. * Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year). * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test NEARLY DONE. The part looks good and will be used but the ones for SR3 and SRM will be made from scratch. * Lower breadboard stuff * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss. * Breadboard springs - 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 * Weigh IM/RM/IRM (Fabian, Hirata) - DONE but anomalies found. * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - from 8/1. * Analyze geophone data (Fabian/Shoda) - data taken by Shoda-san; Fabian to find calibration factors. * Remove glue from dummy BS face (Fabian) - MOSTLY DONE. * Reglue flags and prisms (Tatsumi, Fabian) - from Friday 8/5. * Clean wire for BS and RM (Hirata) - DONE * Get new winch parts for new wire diameters - design received from Ikenoue-san * 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) - ONGOING. * 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) |

Type B (Mark)
Report for week of 1/15
- We set up the QPD for the OL, initialized the OL and TM sections of the RTM, and did TFs from the TM OSEMs to the OL.
- Initially we had no coherence, but we debugged issues with the watchdog, LPCD, and DAC board and then got good TFs.
- We lifted the IM/RM/SR with the load gauge adapter and checked the weight, which was close to the mass budget.
- We installed the section of the AF above the IM, and the BF cross bars and jacks, and craned in the BF.
- We installed the BF-IRM rods, IRM, BF-IM rod, flying saucer and the cable clamps on the bottom of the BF.
- We hooked the IM section, but found it was heavy by several hundred grams. We also noticed the BF keystone had a noticeable tilt of about 1.2 mm (high on the +X side).
- We removed 738 g of trim mass and found that load rose and sat about 2 mm high. So the discrepancy is of order 500-600 g.
- Shoda-san, Enzo and Kozu-kun made and characterized a batch of OSEMs.
- Hirata-san finished drawings for the improved BS PI yaw/vertical adjustment, placed orders for damping ring receptacles and other items, and prepared the second SR BF in case we needed to swap it in.
Plan for week of 1/22
- Fix or swap BF.
- Route selected cables to flange.
- Test IM picos and BF yaw pico.
Plan for week of 1/29
- Enzo at Mitaka 1/29 and most of 1/30, then vacation.
- Kozu-kun away.
- All others at Kamioka.
- Build IRM around IM.
- Cable/test/adjust IM OSEMs.
- Time permitting, do TFs from IM OSEMs to themselves and to optical sensor.
Vacation Info
- Enzo 1/30-2/19 (at Mitaka 1/29, part of 1/30)
- Kozu-kun 1/29-2/2
