| * Type B Past Week Summary * Mark and Fabian worked at Kamioka: * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added. * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction. * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area. * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction. * Hirata-san shipped 7 SFs and some parts to Kamioka. * Hirata-san made assembly drawings of the damper rings and cable clamps for SR. * Hirata-san liaised with Mirapro about the frame assembly. * Type B ongoing issues * Wires * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco. * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables. * Feedthrough Adapters * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote. * Can we make SR wire breakers bigger? * Fukushima-san will start on machining test soon (as of 5/27). * Installation stuff * Crane scale - RECEIVED * Ballast masses for payload * Initial batch received - ordered extra smaller ones to allow for adjustments. * 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: quote from Mirapro received, not urgent, will be combined with assembly frame order. * 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]] |

Type B (Mark)
Report for week of 9/24
- Monday 9/24 was a holiday (Autumn Equinox).
SR2
- We moved all the SR2 feedthrough and in-vacuum and in-air cables.
- We tested all the OSEMs and most of the LVDTs. We still need to run power to the pico drivers, and test them and the steppers.
- We unlocked and mostly realigned the suspension. The IM is sitting lower than before but can be brought up to nominal height with BF GAS offset, without any signs of anything touching. The IM also has a moderately large pitch (2.8 mrad according to the OSEMs, about 1 mrad according to the OL) and some roll, which we expect to be able to correct with some pico adjustment. The horizontal IM OSEMs are well-centered (so there is no yaw misalignment).
SRM
- We made another attempt to set the pitch of the SRM, but weren't satisfied with how close we were able to get (target 20 mm low, achieved 23 mm), so we didn't tighten the clamps or continue to setting the pitch of the RM.
Plan for week of 10/1
- Mark, Hirata-san, Fabian, Panwei at Kamioka Mon-Fri.
SRM
- Set pitch of SRM and RM, tighten clamps, remove winch system.
- Weigh IM/... section.
- Build up SS to BF level.
- Add BF.
- Suspend IM and tweak height/balance.
- Cable/test BF.
- Install IRM.
- Install/cable/test IM OSEMs.
Plan for week of 10/8
- Monday 10/8 is Sports Day.
- Enzo returns Tuesday 10/9.
- Mark and Terrence (plus TBD) at Kamioka Mon-Fri.
- Enzo, Hirata-san, Fabian and Panwei at Kamioka Tue-Fri.
SR2/SR3
- Terrence to set up LEN half of SR3 OL and, time permitting, TILT and LEN for SR2.
SRM
- Continue installation.
To-Do Lists, Schedule
Vacation/Visitor Info
