Small-Signal Behavior of a TES Under AC Bias

Frequency domain multiplexing (FDM) is one of the candidates for the SQUID based readout of TES-based imaging microcalorimeter arrays for applications such as IXO, and imaging bolometer arrays for the SAFARI instrument on the Japanese SPICA space telescope. Usage of the TES as modulating element by...

Description
Summary:Frequency domain multiplexing (FDM) is one of the candidates for the SQUID based readout of TES-based imaging microcalorimeter arrays for applications such as IXO, and imaging bolometer arrays for the SAFARI instrument on the Japanese SPICA space telescope. Usage of the TES as modulating element by applying an AC bias is an essential part of FDM. Within this framework the small signal characteristics of array pixels under both AC and DC bias have been measured. We will present a small signal model of the TES under AC bias, and apply the results to the measurements on an X-ray microcalorimeter.
