Abstract
We demonstrate that a voltage-biased superconducting bolometer (VSB), read out with superconducting quantum interference device (SQUID), can be biased with a sinusoidal voltage. We show that the load curves taken with AC- and DC-bias are nearly identical indicating that there is no identifiable degradation in the performance of the bolometer due to the AC bias. We discuss the use of a frequency-domain SQUID multiplexer with an array of VSB's that are AC-biased.Keywords
