The Scientific Impact of a Noiseless Energy-Resolving Detector for a Future Exoplanet-Imaging Mission
Alex R. Howe, Christopher C. Stark, John E. Sadleir
Future space missions that aim to detect and characterize Earth-like exoplanets will require an instrument that efficiently measures spectra of these planets, placing strict requir…
Transition-edge sensor detectors for the Origins Space Telescope
Peter C. Nagler, John E. Sadleir, Edward J. Wollack
The Origins Space Telescope is one of four flagship missions under study for the 2020 Astrophysics Decadal Survey. With a 5.9 m cold (4.5 K) telescope deployed from space, Origins…
Demonstration of ultra-low noise equivalent power using a longitudinal proximity effect transition-edge sensor
Peter C. Nagler, John E. Sadleir, Edward J. Wollack
Future far-infrared astronomy missions will need large arrays of detectors with exceptionally low noise-equivalent power (NEP), with some mission concepts calling for thousands of…
Towards 100,000-pixel microcalorimeter arrays using multi-absorber transition-edge sensors
S. J. Smith, J. S. Adams, S. R. Bandler +15
We report on the development of multi-absorber transition edge sensors (TESs), referred to as hydras. A hydra consists of multiple x-ray absorbers each with a different thermal con…
Detectors and cooling technology for direct spectroscopic biosignature characterization
Bernard J. Rauscher, Edgar R. Canavan, S. H. Moseley +2
Direct spectroscopic biosignature characterization (hereafter "biosignature characterization") will be a major focus for future space observatories equipped with coronagraphs or st…
Proximity Effects and Nonequilibrium Superconductivity in Transition-Edge Sensors
John E. Sadleir, Stephen J. Smith, Ian K. Robinson +5
We have recently shown that normal-metal/superconductor (N/S) bilayer TESs (superconducting Transition-Edge Sensors) exhibit weak-link behavior.1 Here we extend our understanding t…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
Longitudinal Proximity Effects in Superconducting Transition-Edge Sensors
John E. Sadleir, Stephen J. Smith, Simon R. Bandler +2
We have found experimentally that the critical current of a square superconducting transition-edge sensor (TES) depends exponentially upon the side length L and the square root of…
