Abstract
Superconducting multiplexers make it possible to build arrays of thousands of low-temperature bolometers and microcalorimeters based on superconducting transition-edge sensors with a manageable number of readout channels. Our first generation SQUID multiplexer has now been used in an instrument at the Caltech Submillimeter Observatory. We describe our second-generation SQUID multiplexer, which is based on an architecture that reduces the dissipation of power at the base temperature of the cryostat. We also describe a multiplexer based on "hot electron switches" that is in development.
