This paper presents a comprehensive wave-optics model demonstrating that hollow silicon-carbide corner-cube retroreflectors offer superior mass efficiency and competitive photon return for high-precision lunar laser ranging, while revealing a critical trade-off where smaller apertures are better suited to mitigate flux loss caused by velocity aberration.
The authors present a modular optically detected magnetic resonance (ODMR) setup capable of operating over a two-meter optical path within a commercial helium bath cryostat, successfully demonstrating NV center-based magnetometry and temperature-dependent measurements on samples in constrained cryogenic environments.
This paper presents the design development and initial performance testing of the Gen2-DOM, a new digital optical module featuring 18 photomultiplier tubes and enhanced sensitivity for the IceCube-Gen2 expansion, with twelve prototypes scheduled for deployment in the IceCube Upgrade during the 2025-2026 austral summer.
This paper evaluates and presents GEANT4 simulation results, alongside BINP beam test validations, for three silica aerogel-based RICH detector concepts (FARICH, Fresnel lens RICH, and fiber-based RICH) designed to achieve particle identification up to 30 GeV/c for future colliders like CEPC and FCC.
This paper reports a cryogenic buffer-gas-cell-aerodynamic-lens-stack setup that generates and characterizes controllable beams of shock-frozen nanoparticles, including isolated proteins, enabling their application in single-particle diffractive imaging and low-temperature nanoscience.
This paper investigates the spatial resolution of optically readout MicroPattern Gaseous Detectors using solid wavelength shifters like TPB to enable alternative, non-greenhouse gas mixtures, finding that glass Micromegas with TPB-coated anodes achieve the best resolution of 0.22 mm due to the minimal distance between the scintillation source and the shifter.
This paper presents a direct in-situ comparison of FBK VUV-HD3 and HPK VUV4 SiPMs within the LoLX liquid xenon detector, revealing that HPK devices detect 33–38% less light than FBK devices under operating conditions and demonstrating that this discrepancy is resolved by an optical simulation incorporating angular and wavelength-dependent surface shadowing effects.
This paper demonstrates a breakthrough in superconducting nanowire single-photon detectors by using current-biased superconducting rails to redistribute current, enabling devices up to 0.1 mm wide to reach their intrinsic performance limits with near-unity internal detection efficiency and a ten-order-of-magnitude reduction in dark count rates.
This study evaluates the long-term stability of a single-mask triple GEM detector prototype under 98 days of continuous Fe irradiation, demonstrating consistent gain, efficiency, and energy resolution despite variations in ambient temperature, pressure, and humidity, thereby validating its suitability for large-scale Micro Pattern Gaseous Detector experiments.
This paper presents the development of millimeter-scale, self-assembled SrLuF:Ce3+/Pr3+ core-shell nanoparticle superlattices that function as ultrafast, radiation-hard scintillators with tunable emission and sub-nanosecond decay times, suitable for applications ranging from precision health to hard X-ray imaging at free-electron laser facilities.
