* 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. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) - TM/IM/BF level DONE * 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) |
