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…
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…
Most stringent bound on electron neutrino mass obtained with a scalable low temperature microcalorimeter array
B. K. Alpert, M. Balata, D. T. Becker +36
The determination of the absolute neutrino mass scale remains a fundamental open question in particle physics, with profound implications for both the Standard Model and cosmology.…
A high-speed, high-resolution Transition Edge Sensor spectrometer for soft X-rays at the Advanced Photon Source
Orlando Quaranta, Don Jensen, Kelsey Morgan +12
This project explores the design and development of a transition edge sensor (TES) spectrometer for resonant soft X- ray scattering (RSXS) measurements developed in collaboration b…
