This paper derives the aberration-limiting aperture for specular reflectors and demonstrates through ray tracing simulations that ellipsoidal crystal imagers in symmetric Bragg geometry significantly outperform equivalent toroidal designs by enabling high-resolution, polychromatic hard x-ray imaging with suppressed higher-order aberrations, particularly near backscattering angles.
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.
The paper introduces "AutoDQM," an automated data quality monitoring system for the CMS detector that utilizes unsupervised machine learning and statistical techniques to identify anomalous data at a rate 4 to 6 times higher than that of good data, thereby enhancing the rapid assessment of detector performance.
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.
This paper introduces Synchromodulametry, a hardware-first framework for distributed sensor networks that replaces fragile binary coincidence logic with a real-time coherence-based state variable to maintain meaningful event detection despite detector intermittency and non-idealities.
This study establishes a low-energy ion injection scheme into a gaseous detector and measures the ionization yield of fluorine ions in low-pressure gas, finding a value of 0.45 at 30 keV to improve the accuracy of direction-sensitive dark matter search experiments.
This paper benchmarks quantization techniques and the Google Coral Edge TPU for neutrino interaction recognition, demonstrating that while the Edge TPU offers significantly lower energy consumption than CPUs and GPUs with minimal accuracy loss (particularly for Inception V3), it operates at speeds comparable to CPUs but an order of magnitude slower than GPUs.
This paper details the optimization of the annealing process for large-scale, highly transparent silica aerogel tiles produced in Novosibirsk, presenting the resulting improvements in optical and mechanical properties that enhance their utility for Ring-Imaging Cherenkov detectors in major international experiments.
