Using a high-statistics CsI(Tl) detector and a high-activity Sc source at Texas A&M University, this study employs a "missing-" technique to search for invisible decays in nuclear gamma cascades, thereby excluding specific regions of parameter space for light dark-sector particles such as axions, dark scalars, and dark photons in the 0.1–1 MeV mass range.
This paper proposes a high-speed analog optical readout system for low-temperature experiments that converts electrical signals into light for transmission via optical fiber, offering advantages such as low attenuation, reduced crosstalk, and high bandwidth while maintaining low power consumption.
This paper demonstrates that a high-precision, distributed source can be used to accurately verify the effective mass and volume of an HPGe detector by comparing experimental gamma-ray spectra with Geant4 Monte Carlo simulations.
The XENONnT experiment has reported the first measurement of nuclear recoils from solar B neutrinos using coherent elastic neutrino-nucleus scattering, providing a solar neutrino flux and cross section consistent with Standard Model predictions.
This study details the fabrication and characterization of X-ray transition edge sensors (TESs) using unique annular AlMn alloy films, achieving an energy resolution of 11.0 eV at 5.9 keV.
This paper presents the performance testing of various AstroPix HV-CMOS prototype configurations designed for high-precision gamma-ray imaging in both space-based payloads and the Barrel Imaging Calorimeter of the future ePIC detector.
This paper proposes a U-Net-based deep learning framework to enhance the image quality of short-time Muon Scattering Tomography, significantly improving reconstruction accuracy and similarity to ground truth even when faced with limited muon flux.
This paper demonstrates that a plasma impedance probe (PIP) operated with a controlled DC bias can directly measure sheath thickness in agreement with Child-Langmuir scaling, establishing it as a valid and complementary diagnostic tool to the traditional Langmuir probe.
This study utilizes ultrabroadband photoconduction microscopy and simulations to demonstrate that shallow trap states, specifically Ga-Ga-In oxygen vacancy defects located ~0.32 eV below the conduction band, rigidly control the electrical performance of amorphous InGaZnO thin-film transistors, enabling accurate prediction of transfer characteristics from defect density measurements.
This paper presents the design, fabrication by onsemi, and initial characterization of next-generation 4H-SiC Low Gain Avalanche Detectors (LGADs), demonstrating their fast charge collection, uniform multiplication, and potential as radiation-tolerant sensors for wide-temperature applications.
