Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration
D. A. Bennett, M. Borghesi, P. Campana +17
We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and…
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…
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…
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…
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.…
