Development of a microwave SQUID multiplexer for superconducting transition-edge sensor bolometer arrays
A microwave SQUID multiplexer (μMUX) with a high multiplexing factor is a promising readout approach for large-scale superconducting transition-edge sensor (TES) bolometer arrays. This paper reports on the characteristics of 16-channel μMUX prototype chips and a 60-channel readout module developed to read out TES bolom...
