Paper Abstract
We have designed a detector package to house a superconducting bolometer array, SQUID multiplexers, bias and
integration circuitry, optical filtering, electrical connectors, and thermal/mechanical interfaces. This package has been
used successfully in the GISMO 2mm camera, a 128-pixel camera operating at a base temperature of 270mK. Operation
at lower temperatures is allowed by providing direct heat sinking to the SQUIDs and bias resistors, which generate the
bulk of the dissipation in the package. Standard electrical connectors provide reliable contact while enabling quick
installation and removal of the package. Careful design has gone into the compensation for differing thermal expansions,
the need for heat sinking of the bolometer array, and the placement of magnetic shielding in critical areas. In this
presentation, we detail the design and performance of this detector package and describe its scalability to 1280-pixel
arrays in the near future.
