This paper presents a comparative simulation study using Geant4 and FLUKA to benchmark and optimize a 30 MeV proton-induced beryllium neutron source, evaluating neutron fluence, gamma dose, and moderation effects to guide the design of a modular irradiation station for thermal neutron fields.
This paper generalizes the Semkow summing correction formalism into matrix and partitioned frameworks to analyze 180-degree and gated coincidence events in the GRIFFIN spectrometer, ultimately demonstrating that the statistical deviations inherent in these corrections bound the sufficient measurability of true coincidence summing.
This study demonstrates that a novel converging-pixel CsI:Tl detector fabricated via laser-induced optical barriers, when combined with maximum-likelihood decoding and validated by precise pencil-beam experiments, achieves high spatial resolution and energy performance suitable for advanced SPECT systems.
This paper presents a transformer-based machine learning framework that integrates with four-dimensional scanning transmission electron microscopy (4D-STEM) to rapidly infer nanoscale crystalline microstructures, achieving orientation mapping speeds up to two orders of magnitude faster than traditional template-matching methods.
This paper presents the first demonstration of a high-gain MMThGEM-Micromegas detector in low-pressure SF, achieving a record-breaking negative ion gas gain of approximately and successfully validating its capability for multi-dimensional track reconstruction and nuclear recoil identification in both small-scale tests and a large cubic-meter volume for directional dark matter searches.
This paper presents a wafer-scale packaging architecture capable of supporting over 500 superconducting qubits on a single 3-inch die, demonstrating that large-scale integration can be achieved without compromising device performance while enabling high-throughput metrology for optimizing quantum processor fabrication.
This paper presents new, highly precise measurements of 27 gamma-ray energies between 14 and 136 keV using an ultra-high resolution magnetic microcalorimeter, achieving relative uncertainties as low as 1.3 ppm and significantly improving upon previous literature values for 19 of these energies.
