Abstract

We present recent optical and thermal characterizations of polarization sensitive mm-wave bolometers fabricated at Argonne National Lab. The devices are designed to measure the polarization of the Cosmic Microwave Background and consist of a Mo/Au TES suspended on SiN with a Pd-Au dipole absorber. The detector performance is excellent with >85% co-polar coupling, <1% cross-polar leakage, 36 GHz optical bandwidth, electrothermal loop gains of approximately 10, and NEP ≃50 aWHz-1/2.
