Title: Time-Division SQUID Multiplexers for Transition-Edge Sensors
Published: January 14, 2003
Abstract: Microcalorimeters and bolometers based on superconducting transition-edge sensors (TES) are important tools for the detection of photons from millimeter waves through gamma rays, and for applications ranging from materials analysis to astronomy. There is a great need for large-format arrays of TES detectors to rapidly acquire images and to increase the maximum count rate and collection area for increased statistics. A difficulty in the development of large arrays is the implementation of the cryogenic wiring and electronics to instrument a large number of channels. The heat load and complexity involved in running wires from room temperature to every pixel is prohibitive. To overcome this difficulty, we are developing superconducting electronics to multiplex the readout of microcalorimeters at cryogenic temperatures.
