• Type B Past Week Summary
  • Mark

    • Updated the BS circuit diagram D1503600:

      • Added information on the binary IO.
      • Renamed channels to conform to Okutomi-kun's new scheme.
      • Made the ADC/DAC channel assignment consistent and more logical.
      • Updated the stepper motor sections with info about the new driver chassis.
    • Worked on schedule.
    • Updated the installation procedure with lessons learned from the last few weeks.
    • Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
    • Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
  • Hirata-san
    • Updated the BS 3D Assembly with the new rods and receptacles.
    • Made 2D drawings of SR2 and SR3 (ongoing).
    • Made SRM 3D assembly (ongoing)
    • Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka.
    • Washed screws for hexagon cable clamps and shim rings for Fabian.

Type-Bp (Shoda)

• BFRM

  • The ordering process finished. We told the company to proceed the manufacturing. The detailed discussion with the company will be help at 14th 11:00-.

• New flags

  • We have got the cost estimate. The ordering process is under discussion.

• Flag removing jig

  • The design is fixed. The material will be bought by us and will be passed ATC to machine.

• Cable/Magnets/Cranes

  • The number of the cables used for Type-Bp is checked. Passed information to Takahashi-san.
    The number is enough only for Type-Bp. I am not sure if Type-B and Type-A are included.
    Also we have got the cost estimate for the magnets. They will be ordered soon.
    The chain blocks and lever blocks will also be ordered soon.

• Assembly frame

  • We have got the costestimate. We are asking for the competitive quotes.

• OB related

  • We are going to order the OB related parts necessary in only this FY for now.

• PR3 Disassembly

  • We are going to disassemble the iKAGRA PR3 from 9th. The mirror box and the perican box is sent to Kamioka.

IMMT (Ohishi)

• Put a report here

Watchdog system (Tanaka)
