Measuring the Impact Ionization and Charge Trapping Probabilities in SuperCDMS HVeV Phonon Sensing Detectors
F. Ponce, W. Page, P. L. Brink +12
A 0.93 gram cm SuperCDMS silicon HVeV detector operated at 30 mK was illuminated by 1.91 eV photons using a room temperature pulsed laser coupled to the…
A Spread-Spectrum SQUID Multiplexer
K. D. Irwin, S. Chaudhuri, H. -M. Cho +5
The Transition-Edge Sensors (TES) is a mature, high-resolution x-ray spectrometer technology that provides a much higher efficiency than dispersive spectrometers such as gratings a…
Production Rate Measurement of Tritium and Other Cosmogenic Isotopes in Germanium with CDMSlite
SuperCDMS Collaboration, R. Agnese, T. Aralis +95
Future direct searches for low-mass dark matter particles with germanium detectors, such as SuperCDMS SNOLAB, are expected to be limited by backgrounds from radioactive isotopes ac…
Thermal detection of single e-h pairs in a biased silicon crystal detector
R. K. Romani, P. L. Brink, B. Cabrera +11
We demonstrate that individual electron-hole pairs are resolved in a 1 cm by 4 mm thick silicon crystal (0.93 g) operated at 35 mK. One side of the detector is patterned…
Measurement Of Quasiparticle Transport In Aluminum Films Using Tungsten Transition-Edge Sensors
J. J. Yen, B. Shank, B. A. Young +8
We report new experimental studies to understand the physics of phonon sensors which utilize quasiparticle diffusion in thin aluminum films into tungsten transition-edge-sensors (T…
Nonlinear Optimal Filter Technique For Analyzing Energy Depositions In TES Sensors Driven Into Saturation
B. Shank, J. J. Yen, B. Cabrera +7
We present a detailed thermal and electrical model of superconducting transition edge sensors (TESs) connected to quasiparticle (qp) traps, such as the W TESs connected to Al qp tr…
Demonstration of Surface Electron Rejection with Interleaved Germanium Detectors for Dark Matter Searches
R. Agnese, A. J. Anderson, D. Balakishiyeva +88
The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measu…
Modeling phase-separated transition-edge sensors in SuperCDMS detectors
A. J. Anderson, S. W. Leman, T. Doughty +4
The SuperCDMS experiment implements transition-edge sensors to measure athermal phonons produced by nuclear recoils in Ge crystals. We discuss a numerical simulation of these TES d…
Monte Carlo Comparisons to a Cryogenic Dark Matter Search Detector with low Transition-Edge-Sensor Transition Temperature
S. W. Leman, K. A. McCarthy, P. L. Brink +13
We present results on phonon quasidiffusion and Transition Edge Sensor (TES) studies in a large, 3 inch diameter, 1 inch thick [100] high purity germanium crystal, cooled to 50 mK…
