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…
Phenomenological Modeling of the Ho Calorimetric Electron Capture Spectrum from the HOLMES Experiment
F. Ahrens, B. K. Alpert, D. T. Becker +46
We present a comprehensive phenomenological analysis of the calorimetric electron capture (EC) decay spectrum of Ho as measured by the HOLMES experiment. Using high-statist…
Nuclear Data Needs for Microcalorimetry and Non-destructive Assay
Geon-Bo Kim, Begona Aranguren-Barrado, Shamsuzzoha Basunia +5
Cryogenic microcalorimeters are state-of-the-art radiation detectors using superconducting and quantum technologies. They can resolve complex X-ray and low-energy γ-ray spectra wi…
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…
Demonstration of a 1820 channel multiplexer for transition-edge sensor bolometers
J. C. Groh, Z. Ahmed, J. Austermann +16
The scalability of most transition-edge sensor arrays is limited by the multiplexing technology which combines their signals over a reduced number of wires and amplifiers. In this…
