SNAP NIR Detector Packaging Development:Towards a Universal SiC Detector Package Bruce C. Bigelow Department of Physics, University of Michigan 20 July 2005
SiC NIR Package Design Issues • Neither NIR device vendor is producing a package we want to use for SNAP • SiC is currently favored for SNAP focal plane components • It would be useful to have a NIR package design that can accommodate either RSC or RVS detectors • These designs shown here have the center of the Rockwell sensor area located at the center of the Raytheon sensor area.

Conclusions • A conceptual design for a SiC NIR detector package that could accommodate either Rockwell or Raytheon detectors, and meets all of the current SNAP requirements, has been presented. • Pending review of the quotation drawings, requests for quotations for fabrication of the package will be sent out, and prototype parts will be ordered from at least one vendor B.
