* 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 ([[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. * 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 * 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]] * 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). * 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) |
* Type B Past Week Summary, weeks of 9/19 and 9/26 * Fabian, Mark and Liu-kun did BS installation at Kamioka: * Connected the DIO card to the LPCD. (Simulink model changes will be needed to make use of it.) * Took TF data from the TM-H1 coil output to the voltage and current monitors and found that the response was approximately flat. * Used the 90° prism and the optical lever to set the pitch of the RM to match the dummy BS. * Removed the RM trolley and added the bottom section of the security structure. * Lifted the IM/RM/BS with the load gauge adapter and load gauge and measured its mass. * Hirata-san: * Modified drawing of maraging rods for BS [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5706| D1605706]] * Made 3D models of stub flag gluing jigs. * Made 3D models and 2D drawing of BS BF-IM hexagon cable clamp assembly and cone parts. [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5734| D1605734]] * Washed parts and screws. * (For Type A) Assembled and adjusted blades of BF #9. * Longer term to-do list * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing. * Part "disk security" top has to be modified - screw positions do not match. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of 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]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. |
