Abstract

The upcoming Cosmic Microwave Background (CMB) experiments BICEP2/Keck and SPIDER will be using planar arrays of polarization sensitive antenna-coupled TES bolometers, operating at frequencies between 96 GHz and 220 GHz. At 145 GHz each array consists of 64 polarimeters (128 TES sensors) and four of these arrays are assembled together to make a focal plane. The detector arrays are integrated with a time-domain SQUID multiplexer developed at NIST and read out using the Multi-Channel Electronics (MCE) developed at the University of British Columbia. We present our progress in characterizing focal plane arrays and SQUID multiplexed readout for BICEP2 and SPIDER, describing testing procedures and giving a summary of dark measurements results, as well as preliminary optical measurements
