This paper presents the design, construction, and beam test results of the Muon Trigger Detector (MTD) for the PSI muEDM experiment, demonstrating through experimental data and Geant4 simulations that the system successfully identifies storable muons to enable a sensitivity improvement of over three orders of magnitude in the muon electric dipole moment measurement.
This paper presents two complementary sensitivity enhancement techniques for the NUCLEUS experiment's cryogenic calorimeters—operating point optimization and two-dimensional optimum filter analysis—which, when combined, achieved a baseline energy resolution of 2.94 ± 0.05 eV using a CaWO4 detector.
This paper reports the successful fabrication and first cryogenic operation of two compact n-type germanium ring-contact (GeRC) prototypes, establishing a proof-of-principle workflow for their complex non-planar geometry and demonstrating stable performance at 77 K as a foundational step toward scalable, low-background detectors for rare-event experiments like LEGEND-1000.
This paper experimentally demonstrates a tunable coherence technique using pseudo-random-noise phase modulation to suppress parasitic stray light by 40 dB in laser interferometers while maintaining compatibility with resonant optical cavities.
This paper experimentally demonstrates that the "Tunable Coherence" technique, which controllably breaks a laser's long coherence length, effectively suppresses scattered light noise by 24.2 dB in Sagnac interferometers and offers a fundamental solution for enhancing the sensitivity of ring resonators.
This paper proposes and evaluates a novel single-phase liquid xenon time projection chamber for medical PET imaging, demonstrating through simulations that its superior energy resolution and intrinsic 3D position sensitivity enable significantly better spatial resolution (~1 mm vs. ~4 mm) and scattered event rejection compared to conventional LYSO-based systems.
This paper presents a comprehensive noise analysis of waveguide-based squeezed-light sources, demonstrating that their robustness and low intrinsic noise make them a promising alternative to cavity-based systems for quantum-enhanced applications like future gravitational wave detectors, particularly when employing a cascaded architecture to mitigate loss-induced degradation.
This paper demonstrates the near-term feasibility of deploying quantum-inspired tensor network algorithms, specifically a spaced matrix product operator and its cascaded variant, on FPGA hardware to enable real-time anomaly detection for beyond-Standard-Model physics at particle colliders.
This paper presents CaloScore v2, an improved diffusion-based model for fast calorimeter shower simulation that utilizes progressive distillation to achieve high-fidelity sample generation with a single function evaluation, thereby overcoming the computational bottlenecks of traditional diffusion processes.
This paper reports the successful characterization of an FBK NUV-HD-cryo silicon photomultiplier operated at 9.4 mK within a dilution refrigerator, demonstrating its viability for detecting cosmic-ray muons in low-background dark matter experiments like QUEST-DMC.
