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…
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.…
The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
System performance of a cryogenic test-bed for the time-division multiplexing readout for NewAthena X-IFU
Davide Vaccaro, Jan van der Kuur, Paul van der Hulst +23
The X-ray Integral Field Unit (X-IFU) is an instrument of ESA's future NewAthena space observatory, with the goal to provide high-energy resolution ( 4 eV at X-ray energies up t…
