Progress report
Type-A (Takahashi)
Vacuum compatibility of the release sensor was checked by Saito-san.
Type-B (Mark)
- 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 re-greased 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.
- Fabian designed modifications for the brackets on the security structure for immobilizing the IM, and Hirata-san did 2D drawings from them.
- 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.
- Hirata-san measured another filter and cleaned parts for Fabian
- 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.
