| * 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)
Past week report
At Kamioka (Mark, Fabian, Enzo, Perry, Hirata-san):
- We set things up again after the floor coating work.
- We moved the PI into the second floor of the cleanbooth:
- We cleared a path for the forklift (moving the portable cleanroom, worktable, power cables, vacuum pumps and other obstacles).
- We got Saito-sensei to move the PI to the +Y side of the cleanbooth.
- We washed and cling-wrapped a pallet.
- We got Miyoki-san to disconnect the cables and curtain blocking the crane slot (and reconnect them afterwards).
- We added some temporary crossbars in the top of the assembly frame and stored the SF cap on them to get it out of the way.
- We craned in the pallet and set it up to bridge three floor joists.
- We craned in the PI using Saito-san's adapter.
- We couldn't find the original screws for the three PI transport plates so we substituted some others - fortunately there was no galling.
- We had to connect the adapter to the crane with a sling because the ring for the hook was slightly too small).
- We did a lot of cabling work:
- We routed all the BF cables over the BF cap, up through the cable clamp on the SF-BF rod and up to the SF. (We had to redo a few because the Type 3 cable was at the flange end instead of the Type 1.)
- We connected up the SF LVDT and FR stepper.
- We started on rebalancing the BF (which had been perturbed by the weight and tension of all the cables). We got it rather better, but it needs more work.
- We made another batch of anti-feedthrough adapters.

- Debug BF/SF LVDTs.
- Adjust BF pitch/roll.
- Do TF from SF LVDT actuation.
- Install temporary ballast mass in SF.
- Lift SF/BF/... section and check total weight and SF balance.
Continue swap of PI LVDT connectors (female->male)
- Start preparing LBB spring units.
- Install pico drivers in rack, create MEDM interface (with Miyo-kun), and undo temporary connection of picos to old controller and joystick.
Week of 4/17:
