Superconducting Multiplexers for Transition-Edge Sensors

June 1, 2003
Author(s)
Kent D. Irwin, James A. Beall, Joern Beyer, Steven Deiker, W.Bertrand (Randy) Doriese, S. L. Ferreira, Gene C. Hilton, Sae Woo Nam, Carl D. Reintsema, Joel Ullom, Leila R. Vale
Superconducting multiplexers make it possible to build arrays of thousands of low-temperature bolometers and microcalorimeters based on superconducting transition-edge sensors with a manageable number of readout channels. Our first generation SQUID

Surface Micromachining for Transition-Edge Detectors

Author(s)
Gene C. Hilton, James A. Beall, Steven Deiker, Joern Beyer, Leila R. Vale, Joel Ullom, Kent D. Irwin
We are developing arrays of high performance detectors based on superconducting transition-edge sensors (TES) for application in x-ray materials analysis as well as x-ray and sub-mm astronomy. In order to obtain the desired thermal time constants, as well

Time-Division SQUID Multiplexers for Transition-Edge Sensors

Kent D. Irwin, James A. Beall, Joern Beyer, Steven Deiker, W.Bertrand (Randy) Doriese, S. L. Ferreira, Gene C. Hilton, Sae Woo Nam, Carl D. Reintsema, Joel Ullom, Leila R. Vale
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

Large-Area TKIDs for a New Generation of Neutron Beta Decay Experiments

January 1, 2001

Elizabeth Scott, Jimmy P. Caylor, Maynard S. Dewey, Jiansong Gao, Colin A. Heikes, Shannon Hoogerheide, Hans Pieter Mumm, Jeffrey S. Nico, Joel Ullom, Michael Vissers
Nuclear physics has long played a central role in our efforts to better understand the natural world. Several experiments are well positioned to improve limits in searches for physics Beyond the Standard Model (BSM). Many of the experiments in nuclear
