Abstract

We present new data on feedhorn-coupled transition-edge sensor devices fabricated for the second-generation receiver (ACTPol) for the Atacama cosmology telescope (ACT). First, we describe optical efficiency measurements of the latest ACTPol detector wafer, which has a \(86\,\pm 15\,\%\) average optical efficiency. Next, we discuss measurements of the TES resistance as a function of temperature and bias current (\(R(T,I)\)) using the ACTPol time-domain multiplexing electronics. Qualitative agreement between \(R(T,I)\) data at low bias current and the two-fluid model prediction is shown. Using the two-fluid model and low bias current \(R(T,I)\) data, \(\alpha \) and \(\beta \) at our operating bias current are calculated.
