Line 7: Line 7:
   * 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, meaning that meaningful TFs can be taken of the RM/BS stage with no DIO.
   * 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.
   * Built up the security structure to the ring below the BF.
   * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
   * Craned in the BF.
   * Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.)
  * Hirata-san:
   * Made 3D models of (revised) stub flag gluing jigs.
   * (For other groups)
    * Assembled two BFs.
    * Made drawings of PRM inner frame.
Line 19: Line 17:
  * Mark worked on schedule but only succeeded in completely garbling the Type B section of the VIS schedule on the server.   * Mark worked on schedule.
  * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors was completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which corrects them.

  • Type B Past Week Summary
    • Fabian, Mark and Liu-kun did BS installation at Kamioka:
      • Built up the security structure to the ring below the BF.
      • Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
      • Craned in the BF.
      • Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.)
    • Hirata-san:
      • Made 3D models of (revised) stub flag gluing jigs.
      • (For other groups)
        • Assembled two BFs.
        • Made drawings of PRM inner frame.
    • Mark checked lots of drawings by Hirata-san.
    • Mark worked on schedule.
    • Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors was completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which corrects them.
  • Longer term to-do list
