This Letter of Intent outlines a proposal to develop a future experiment at the High-Intensity Muon Beam facility at PSI, aiming to improve current sensitivity by over an order of magnitude within the next decade to maintain leadership in searching for charged lepton flavor violation.
This paper introduces LANTERN, an optical calibration system utilizing a fast-switching LED matrix to characterize low-threshold cryogenic detectors in the 10 eV to 1 keV range without radioactive sources, demonstrating its effectiveness through validation tests on the BULLKID-DM and CALDER experiments that achieved approximately 2% energy-reconstruction accuracy.
This paper proposes and analyzes a novel, compact three-lens optical system called the Range Emulator, which effectively reproduces long-distance laser propagation effects on a laboratory scale while quantifying the trade-off between system size and manufacturing precision to support future intersatellite link testing.
This paper presents a first-principle model explaining low-energy radon-induced backgrounds from electrode grids in dual-phase xenon TPCs, which aligns with data from the LZ and LUX experiments and offers strategies for mitigating these backgrounds in future dark matter searches.
This paper proposes a magnetic dipole-dipole interaction mechanism, characterized by an distance dependence and simultaneous spin flips of donor and acceptor electrons, as a new long-range resonance energy transfer pathway that enhances scintillation quenching in liquid scintillators containing oxygen or heavy-element organic molecules.
This paper presents a systematic Monte Carlo-based uncertainty propagation analysis for a spherical magnetic field camera, quantifying how sensor calibration and positioning errors impact the spatial distribution of field estimation uncertainty to identify dominant error sources and assess the robustness of spherical harmonic methods.
This paper presents the optical design and sensitivity optimization of the 2.5 m CHRONOS, a cryogenic triangular Sagnac speed-meter interferometer that achieves a quantum-noise-limited strain sensitivity of approximately at 1 Hz through optimized mirror configurations and recycling techniques, serving as a scalable laboratory testbed for future sub-hertz gravitational wave detection.
This study investigates the isothermal annealing behavior of neutron-irradiated p-type silicon pad diodes from 8-inch wafers across a range of fluences and temperatures to extract annealing time constants, thereby improving the Hamburg model's ability to predict long-term radiation damage effects in the CMS High-Granularity Calorimeter sensors for the High-Luminosity LHC.
This study presents a direct in-chamber measurement method for 220Rn (thoron) emanation that minimizes transfer losses and achieves a fivefold sensitivity increase over conventional flowthrough setups, offering an effective tool for background control in rare-event physics experiments.
This paper establishes a methodological foundation for designing electrostatic MEMS-based electron optics by developing an accurate analytical and numerical model for thin electrodes with fringing fields, which was validated through the design, fabrication, and characterization of a spiral phase plate capable of generating high-quality vortex beams.
