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±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, α and β at our operating bias current are calculated.
