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
