HSC fits IAA’s interests both in the science and technical sides


Our role in hsc
Our Role in HSC

  • Mechanical Shutter

  • Filter exchanger

  • CCD emulator?

  • Optical and Mechanical components?

  • Tight space and weight limits of the HSC makes it challenging


    Specifications for shutter
    Specifications for shutter

    • Time Repeatability : 1%

    • Time Accuracy : 0.01 s

    • Shortest exposure time : 1s

    • Maximum Speed : 800 mm/s

    • Operation Temperature : -10 to 10C

    • Weight ~25Kg

    • 15mm thickness at shutter body and 120mm diameter of the drums


    Major activities in iaa
    Major activities in IAA

    • Extract system design and specifications form Subaru last June

    • HSC team formed in IAA

    • ARL to be the major contractor for the two systems

    • Fabric material purchased for strength test

    • Regular meeting with ARL


    Aeronautical research lab arl
    Aeronautical Research Lab. (ARL)

    • Government funded Military research laboratory

      • Major jet fighter development center in Taiwan

    • Long term collaboration on the SMA project with good partner spirit.

    • Main contractor carrying out the ALMA EA FEIC.
