Improved aluminum film transport properties and enhanced TES response in athermal phonon detectors: implications for quasiparticle dynamics
Mahdi Mirzakhani, Keith Hunter, Rupak Mahapatra +1
Our detectors for Dark Matter and Coherent Elastic Neutrino--Nucleus Scattering (CENS) use photolithographically patterned superconducting athermal phonon sensors that are coupl…
Characterization of a CsI(Tl) Scintillator Coupled to a SiPM at Cryogenic Temperatures
M. Mirzakhani, R. Mahapatra, M. Platt
We report on the scintillation characterization of a 1 cm^3 CsI(Tl) crystal coupled to a 6 x 6 mm^2 SiPM read out with a custom transimpedance amplifier at cryogenic temperatures.…
Search for dark matter Particles via Invisible Decays in Sc Nuclear Cascades with a CsI(Tl) Detector
Sharada Sahoo, Jing-han Chen, Mahdi Mirzakhani +3
Dark matter remains one of the most compelling open problems in modern physics, motivating experimental searches for new light, weakly coupled particles beyond the Standard Model.…
A GEANT4-Based Simulation of Directional Neutron Detectors Using Liquid Scintillators and Boron Carbide Moderators
J. -H. Chen, M. Mirzakhani, R. Mahapatra +1
We present a simulation-based study of a compact directional neutron detector composed of liquid scintillator, Cesium Iodide, with boron carbide (B4C) moderation, and silicon photo…
Measurement of Low Energy Nuclear Recoil Events with the phonon-mediated Voltage-Assisted Hybrid Detector for Rare Event Searches
Sandro Maludze, Mahdi Mirzakhani, William Baker +7
The phonon-mediated hybrid detector is made out of a monolithic silicon crystal characterized by two interconnected regions linked through a narrow neck. Operating solely on phonon…
