Title: Standardized CCD and MCT detector mounting configurations


1
Standardized CCD and MCT detector mounting
configurations
  • B. C. Bigelow, UM Physics
  • 2/2/05

2
Common detector packages
  • Objectives
  • Build on previous UM focal plane work (see BSCW
    or http//www.physics.lsa.umich.edu/bigelow/snap/i
    ndex.html)
  • Standardize visible and IR detector package
    details including
  • Package to focal plane mechanical interface 3
    point contact
  • Electrical connectors
  • Filter mounts
  • Accommodate detector package CTE differences
  • Enable multiple material choices for focal plane
    base plate
  • Follow the HDH focal plane specifications
  • Acknowledgements
  • Heritage from GL Scientific H2RG package
    Thanks Gerry Luppino!

This presentation
  • Outline
  • Why Hypertronics connectors?
  • Standardized visible package
  • Standardized IR package

4
Electrical connectors
  • Hypertronics Corp. is a division of Smiths Group
    (UK)
  • US offices in Hudson, MA, and St. Louis (custom
    designs)
  • Multiple space-rated connector options
  • KA series - 2/3 row style, 0.6mm pins (4A),
    2.54mm staggered pitch
  • KA series - 4/5 row style, 0.6mm pins (4A),
    2.54mm square pitch
  • HPH series multi rows, 0.6mm pins (4A), 1.905mm
    staggered pitch
  • Multiple material choices
  • KA series Diallyl Phthalate standard
  • HPH series Polyphenylene Sulphide
  • PEEK is a common option (oil field connectors)
  • Various glass-filled PEEK options are available
  • Testing required for 140K operation?
  • Custom connectors are regular part of
    Hypertronics business

Common detector packages
  • Conclusions
  • Standardized visible and IR detector package
    designs shown
  • Mountings enable alternate material choices for
    focal plane base plate
  • Designs follow HDH focal plane specs (mostly!)
  • Belleville disc spring preloading enables
    baseplate material choices
  • Intermixing of CCD and MCT detectors remains an
    open issue
  • What is minimum allowable gap between packages?
  • Does detector readout direction influence
    orientation in focal plane?
