Abstract

We present progress on Argonne/KICP TES bolometers fabricated at Argonne National Labs. These detectors will be used to measure the polarization of the Cosmic Microwave Background radiation with SPTpol. The sensors are bolometers consisting of a Mo/Au transition edge sensors (TES) suspended on silicon nitride with a gold bar absorber to couple radiation to the device. We present optical measurements and thermal characterizations of prototype devices.
