This Geant4 simulation study validates the ePIC experiment's dRICH detector design by demonstrating that the n=1.026 aerogel radiator significantly enhances high-momentum -K separation while quantifying the moderate impact of SiPM dark noise on performance thresholds.
This paper presents the development and characterization of a compact microchannel-plate detector for the WISArD experiment at ISOLDE/CERN, demonstrating its ability to achieve sub-millimeter beam profile measurements with pincushion distortion correction under a 4 T magnetic field to support the extraction of the beta-neutrino angular correlation coefficient with 0.1% uncertainty.
This paper demonstrates that an 8x8 FET-based terahertz detector array, fabricated in a 65-nm Si-CMOS process and operated in a compact liquid-nitrogen-cooled cryostat, achieves high sensitivity and wide dynamic range comparable to superconducting sensors, making it an ideal solution for space-constrained missions where deep cryogenic cooling is impractical.
This paper presents a comprehensive Monte Carlo simulation framework using coupled \textsc{mute} and \textsc{geant4} tools to characterize muon-induced neutron backgrounds at the shallow-underground CURIE facility, providing site-specific flux predictions and a validated depth-intensity relation to guide experimental design for low-background physics.
This paper demonstrates that hybrid photon counting detectors (HPCDs) enable fast, lab-based nanoscale x-ray tomography, achieving an 800-fold speedup and 75–80 nm spatial resolution for imaging 130-nm node integrated circuits compared to previous methods.
This paper demonstrates that the glass scintillator SG101 is a promising candidate for high-efficiency thermal neutron detection and precise event tagging, exhibiting superior pulse shape discrimination performance and significant physical correlations when coupled with organic scintillators like EJ200 and EJ276.
The authors report the first successful demonstration of an annular AlMn Transition-Edge Sensor (TES) for X-ray detection, achieving a record-breaking energy resolution of 12.1 eV at 17.48 keV (below 0.1%), thereby validating AlMn alloys as a promising alternative to traditional bilayer TESs for high-resolution X-ray spectrometry.
This paper introduces TRED, a sustainable and extensible GPU-accelerated simulation package for pixelated time projection detectors that utilizes Gaussian quadrature for effective-charge calculation and a sparse block-binned tensor representation to enable efficient, low-memory FFT-based signal computation for sparse detector volumes.
This paper presents a compact, modular environmental control chamber featuring an adjustable magnetic field and precise solvothermal vapor annealing capabilities, designed to facilitate versatile in situ and ex situ GISAXS studies of thin film self-assembly in both laboratory and large-scale facility settings.
This paper presents a method for unconditional full vector magnetometry using Nitrogen Vacancy centers in diamond that determines both the magnitude and direction of external magnetic fields without prior knowledge, by exploiting spin selectivity through elliptically polarized microwave fields and specific spatial arrangements.
