  • Type B Past Week Summary
    • 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 (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 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.

  • Type B ongoing issues
    • OSEMs
      • 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.
    • 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 - RECEIVED.
    • Documents
  • To-do list during Mark's vacation
    • Apply grease to jacks for assembly frame (Takahashi)
    • Finish assembly of BS IM, RM and IRM (Fabian).
    • Weigh IM/RM/IRM (Fabian, Hirata)
    • Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian).
