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