  * Fabian finished dummy BS assembly.
  * Mark and Tatsumi-san glued magnets into both types of BS optic flags, and discs into BS IM flags. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1815 |klog]] Two optic flags had to be redone because the magnets moved while the glue was drying. Hirata-san helped remove the magnets with acetone in the ultrasonic cleaner. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1818|klog]]
  * Tatsumi-san, Fabian and Mark took the dummy BS to Kashiwa and glued the flags and prisms. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1821|klog]] We will check status on Mon 6/13.
  * Hirata-san moved in another filter for testing (but didn't get to measure it).
  * Hirata-san washed a batch of parts.
  * Hirata-san modified the design of the parts of the assembly frame supporting the BF and SF to include bushings for smoother movement.
  * Hirata-san researched and ordered a crane scale for use at the site. (We decided the 500-kg version of the 200-kg one used at TAMA. It is the same price and has the same 100-g resolution for the first 250 kg.)
  * Hirata-san worked on making some guide parts for the PI installation (Misumi parts with minor additional machining from ATC).
  * We finalized a design for simple SS mirror parts for the dummy BS with Akutsu-san. They will be made by ATC.
  * Mark worked on list of items for purchase in FY2016 and on the schedule.
  * Fabian did more work on the IM assembly. It is nearly done and he will start on the RM next week. There were some issues with crimping connectors to wires for making pico adapter cables.
  * 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.

  * 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).
  * Not enough crane height problem (Hirata, Saito) - no action since last week
  * Installation stuff
   * Crane scale - quote received
   * Work platforms - quote received
  * Ballast masses for payload
   * Initial batch received - ordered extra smaller ones to allow for adjustments.
   * 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.
Line 34: Line 28:
   * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
  * Clean bag - expected 6/8.
   * Nail-head parts - RECEIVED.
Line 38: Line 31:
  * To-do list for Fabian/Hirata-san during Mark's vacation
   * 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)
