This study characterizes low $dI/dt$ X-pinch plasmas by correcting for AXUV photodiode nonlinearities and applying the Bennett relation, revealing that the soft x-ray source is a "bright spot" with a density of and temperature of , rather than an extremely compressed "hot spot."
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 study demonstrates that machine learning-optimized binary voxel masks trained on one CdZnTe spectrometer can generalize effectively to other detectors with only a marginal performance loss, suggesting that a single common mask can significantly reduce the labor and data collection efforts required for optimizing multiple spectrometers in safeguards applications.
This paper presents a unified approach for estimating total optical cavity losses by comparing direct measurements from the Caltech 40m prototype interferometer with numerical simulations based on mirror surface profiles, aiming to minimize decoherence and enhance sensitivity in quantum-enhanced precision metrology.
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 a compact, magnetless isolator utilizing a flux-pumped, dispersion-engineered transmission line to achieve broadband isolation (20 dB across 4–8 GHz) comparable to conventional ferrite devices, offering a scalable solution for co-integration with large-scale superconducting systems.
This paper introduces a differentiable conditional denoising-diffusion surrogate for electromagnetic calorimeter simulations that achieves high-fidelity energy-deposition maps with minimal retraining via Low-Rank Adaptation and provides accurate gradients for gradient-based detector design optimization.
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.
