• Type B Past Week Summary
  • Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:

    • Calculated BS pitch correction (JGW-T1605630)

    • Hung dummy optic and set pitch.
    • Prepared RM for hanging (adding OSEMs etc). One OSEM (#24) had wobbly leads and was brought back to Mitaka for rework.
    • Placed vacuum feedthroughs on assembly frame and cleaned initial batch (4) of D-Sub cables.
    • Decided position of BS rack with Miyakawa-san.
    • Measured various maraging rods and the rod holders on the SF.
    • Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  • Hirata-san:
    • Made new 3D models of the maraging rods for PRx and SRx
    • Made new collet design for PRx and SRx (3D and 2D).
    • Made new IM flag design for PRx and SRx (3D and 2D).
    • Washed lots of Type A BF parts and OSEM parts.
    • Cleaned the BS BF-IM maraging rod and organized the rest of the stock of rods.
    • Measured some BF part dimensions.
    • Pre-assembled parts for BFs.
• Type B ongoing issues
• Longer term to-do list
  • Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
    • 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 E1504235, 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)
  • 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)
