Broad-band High-Energy Resolution Hard X-ray Spectroscopy using Transition Edge Sensors at SPring-8
Shinya Yamada, Yuto Ichinohe, Hideyuki Tatsuno +40
We have succeeded in operating a transition-edge sensor (TES) spectrometer and evaluating its performance at the SPring-8 synchrotron X-ray light source. The TES spectrometer consi…
Design of a mission to measure the shape and substructure of the 511 keV gamma-ray line from the center of the Milky Way
Kun Hu, Matthew Fritts, Daniel Becker +23
The 511 keV electron-positron annihilation feature near the galactic center has been detected for more than half a century, yet its origin remains a mystery. In this paper, we desc…
Imaging the Superconducting Proximity Effect in S-S'-S Transition Edge Sensors
Austin R. Kaczmarek, Samantha Walker, Jason Austermann +11
Proximity effects at superconducting interfaces, between different superconductors (S-S') or between superconductors and normal metals (S-N), are fundamental to the performance of…
Using a 4-megapixel hybrid photon counting detector for fast, lab-based nanoscale x-ray tomography
Jordan Fonseca, Zachary H. Levine, Joseph W. Fowler +8
Hybrid photon counting detectors (HPCDs) have unlocked new capabilities for x-ray-based measurements at synchrotrons around the world in the last 30 years. By leveraging independen…
Characterization of Silicon-Membrane TES Microcalorimeters for Large-Format X-ray Spectrometers with Integrated Microwave SQUID Readout
Avirup Roy, Robinjeet Singh, Joel C. Weber +17
We present the electro-thermal characterization of transition-edge sensor (TES) detectors suspended on Si membranes fabricated using a silicon-on-insulator (SOI) wafer. The use of…
Lithographic integration of TES microcalorimeters with SQUID multiplexer circuits for large format spectrometers
Robinjeet Singh, Avirup Roy, Daniel Becker +12
Arrays of hundreds or thousands of low temperature detectors have been deployed for many experiments, both bolometers for long wavelength applications and calorimeters for shorter…
