This paper investigates the progressive gain degradation observed in the ICARUS detector's cryogenic photomultiplier tubes, characterizes the irreversible performance loss at low temperatures through experimental testing and modeling, and implements mitigation strategies to ensure reliable operation.
This paper demonstrates that deep-learning-based trigger algorithms, particularly a supervised neural network and an MPDR-based anomaly detection model, significantly outperform traditional hit-count triggers in identifying low-energy neutrino events for the Hyper-Kamiokande experiment while maintaining real-time feasibility with sub-millisecond GPU inference latencies.
This paper proposes that the low-energy excess observed in cryogenic calorimeters arises from surface dislocations nucleated by thermal contraction mismatches between the absorber and underlying SiO layers, offering a solid-state explanation and suggesting detector design modifications to test and mitigate this background.
This paper characterizes spurious charge in SENSEI Skipper-CCDs, identifying the serial register as the dominant background source during readout and demonstrating that a novel "tri-level" clocking scheme reduces single-electron density by a factor of approximately seven.
This paper proposes a novel fiber-based Sagnac interferometer to perform a precision terrestrial measurement of the Shapiro time delay, aiming to determine the PPN parameter gamma with a sensitivity of 10⁻⁹ and thereby provide an independent laboratory-scale test of General Relativity.
This paper introduces and experimentally validates Spin Phase Continuous Modulation (SPCM), a novel method utilizing oscillating magnetic fields to precisely characterize the velocity and monochromaticity of neutron beams.
This paper presents a theoretical formulation and experimental validation using neutron spin interferometry for analyzing multi-frequency oscillating magnetic fields, demonstrating that such fields cause contrast decay due to Larmor precession dispersion and result in non-constant interference phases.
This paper presents a scalable neuromorphic approach using event-based cameras to simultaneously track and actively cool the motion of three uncoupled levitated microspheres, demonstrating a pathway toward large-scale arrays for precision sensing and quantum applications.
This paper presents the first experimental demonstration of using single-molecule magnet crystals to detect particle scattering via induced magnetic avalanches, establishing a new platform for high-efficiency quantum energy detection that could be optimized for sub-eV applications.
Simulations confirm that the carbon steel rebars and TT bridge in the JUNO detector structure do not significantly compromise PMT detection efficiency, as the resulting residual magnetic fields remain within the experiment's acceptable limits of 10% for CD-PMTs and 20% for Veto-PMTs relative to the geomagnetic field.
