This paper presents a minimal-component, transformer-free full-duplex digital link over a single coaxial cable that achieves reliable 100 MHz bidirectional transmission with sub-nanosecond jitter by utilizing a passive resistive hybrid and standard logic components, making it ideal for space-constrained laboratory instrumentation.
This paper presents the first measurement of phonon bursts caused by fast neutron damage in solid-state calorimeters but concludes that such bursts do not dominate the low-energy event excess observed in dark matter and neutrino searches, based on differences in spectral shape, thermal history dependence, and exposure scaling compared to control detectors.
This paper presents a prediction method for PMT afterpulse rates in the SUBMET experiment that achieves approximately 20% precision, thereby enhancing the reliability of background predictions for the search of millicharged particles.
This paper introduces a Bayesian protocol that combines full-spectrum template matching with probabilistic evidence evaluation to successfully identify single- and two-source neutron configurations from recoil and time-of-flight spectroscopy data with high statistical significance, even at low event counts.
The Dandelion experiment presents its first results searching for 1 meV dark photon dark matter using a spherical mirror and a 221-KID array, finding no signal and establishing the first millimeter-wavelength upper limits on dark photon kinetic mixing between 0.6 and 1.4 meV after successfully mitigating background noise through de-correlation analysis.
This paper extends previous bounds on the axion-photon coupling by over an order of magnitude using the SACLA X-ray free electron laser and the Borrmann effect in Laue crystals, achieving the most stringent laboratory constraints to date for QCD axions in the 3.46–3.48 keV mass range.
This paper addresses the fabrication challenges of on-chip superconducting integral field units for CMB and line-intensity astronomy by introducing novel components and techniques—including polarization-sensitive crossovers, optimized lithography, dielectric layer deposition, and yield-improving short removal—to successfully fabricate a fourteen-spaxel spectrometer array.
This paper introduces a novel molecular dynamics simulation approach that overcomes traditional Lindhard model limitations by incorporating crystal condensed matter effects to accurately predict ultra-low energy ionization yields in semiconductor detectors, thereby extending dark matter exclusion limits to 0.29 GeV/.
This paper proposes a kaleidoscopic scintillator design that uses mirror reflections to amplify light collection from individual high-energy particle events, enabling high-resolution 3D imaging and machine vision analysis using commercial single-photon cameras despite the challenge of extremely low photon counts.
This paper summarizes the main features, Run-3 performance, and physics impact of the upgraded ATLAS Trigger system, which was enhanced to handle increased luminosity and pile-up conditions while reducing the event rate for offline analysis.
