Abstract

We present initial test results for far-infrared arrays built at the University of Arizona using Ge:Ga photoconductors and low temperature readouts operating at a temperature of 2 K. We also present separate test results for the Hughes CRC-696 multiplexer used in this program. The two array configurations considered are a 1 X 32 based on an older heated readout concept and a new 4 X 32 module that takes advantage of the benefits of having a true cryogenic readout. Based on these results, performance meeting the SIRTF goal of background-limited imaging can be expected for the 32 X 32 array under construction.
