The readout of transition-edge sensor (TES) bolometers with a large multiplexing factor is key for the next generation Cosmic Microwave Background (CMB) experiment, Polarbear-2, having 7,588 TES bolometers. To enable the large arrays, we have been developing a readout system with a large multiplexing factor in the frequency domain. Our goal is to have a readout system, which reads out TES bolometers through a single superconducting quantum interference device (SQUID) with 40x multiplexing. This paper focuses on cryogenic readout and describes how it affects performance of the readout. We will present status of the cryogenic readout for Polarbear-2 experiment. |
