This paper reports on the successful four-year operation of an instrumented baffle installed at the Advanced Virgo Plus Input Mode Cleaner, demonstrating its effectiveness in monitoring stray light and laser stability without introducing additional noise to the interferometer.
This paper presents a software-defined radio implementation using quadrature amplitude modulation (QAM) on an UltraScale+ RFSoC platform to generate high-fidelity phase-modulated signals that enable continuous frequency tuning in electronic sideband Pound-Drever-Hall laser locking while compensating for I/Q impairments to achieve sub-0.3% error rates.
This paper introduces and validates the concept of crossed laser phase plates (XLPP) for transmission electron microscopy, demonstrating through theory, simulation, and prototype experiments that intersecting laser standing waves enhance low-frequency image contrast for biological specimens while suppressing unwanted diffraction artifacts.
This paper establishes a comprehensive framework for Deep Frequency Modulation Interferometry (DFMI) that quantifies fundamental precision limits and identifies previously unrecognized "valleys of robustness" where systematic biases are suppressed, thereby providing a consolidated error budget and quantitative design paradigm for absolute length metrology.
This paper presents a theoretical framework for a novel microcalorimeter utilizing phonon-blocked superconducting tunnel junctions with integrated on-chip cooling and phonon isolation, demonstrating its potential to achieve superior energy resolution and rapid thermal response that rivals or exceeds state-of-the-art transition-edge sensors.
This paper presents the design, construction, and characterization of a compact, water-cooled Bitter-type electromagnet that utilizes stacked copper arcs with PTFE spacers to generate an optimized magnetic field for Zeeman slowing, achieving rapid electrical switching and efficient thermal management at 200 A.
The CDEX-10 experiment at the China Jinping Underground Laboratory reports the first search for ultraheavy dark matter using p-type point-contact germanium detectors, setting the most stringent constraints to date on spin-independent scattering cross sections for masses between and GeV based on an analysis of 205.4 kgday of data with no observed excess above background.
The Super-Kamiokande experiment has successfully upgraded with gadolinium to enable efficient neutron tagging, significantly enhancing its sensitivity to the diffuse supernova neutrino background and other neutrino sources while achieving world-leading limits on DSNB flux.
This paper presents first test beam results from a small-scale GRAiNITA prototype at CERN, demonstrating that the detector achieves a non-uniformity constant term below 1% and a photo-electron statistics contribution of approximately 1%/√E, thereby validating its expected calorimetric performance for future full-scale designs.
The authors developed and validated a semiautomatic system combining robotics, high-resolution imaging, and image analysis to efficiently screen 1 cm³ plastic scintillator cubes for future neutrino detectors, achieving 10 μm precision, over 80% consistency with manual screening, and a 3.1% rejection rate.
