Abstract

The demonstration of a microwave SQUID multiplexed readout of transition-edge sensor (TES) microcalorimeters has the potential to dramatically expand the scale of arrays of TESs. In this manuscript we discuss recent work to develop an instrument for high-resolution, high-efficiency gamma-ray spectroscopy that integrates previously demonstrated high-resolution TES micro-calorimeters with new lower noise microwave SQUID multiplexers. We will discuss the proposed instrument design and readout noise of the optimized microwave SQUID multiplexed readout. Finally we will discuss the potential limits on the number of multiplexed TESs imposed by our exiting analog to digital converter.
