This paper reports on the successful conversion of the Manitoba II mass spectrometer into a versatile, steerable low-energy proton beam facility (25–35 keV) capable of characterizing silicon detectors for BSM searches like the Nab experiment by delivering a monoenergetic pencil beam with a 0.6–1.26 mm spot size over a 117 mm area.
This paper presents a study on optimizing various neural network architectures (Dense, CNN, and Dense+RNN) with Bayesian procedures and Deep Evidential Regression to run on ATLAS calorimeter FPGAs, achieving superior energy resolution and accurate uncertainty estimation compared to current methods under high pile-up conditions expected at the HL-LHC.
This paper presents an analysis of over two tonne-years of CUORE data demonstrating that optimized selection techniques enable the experiment to effectively explore the keV-scale energy region with improved resolution and reduced background, thereby validating tonne-scale cryogenic calorimeters as versatile tools for rare event and dark matter physics across a wide energy range.
This paper proposes and evaluates a complementary missing-energy search strategy using the LDMX Electromagnetic Calorimeter as an active target during early running, demonstrating sensitivity to light dark matter candidates with effective interaction strengths as low as for masses around 1 MeV.
This paper reports the successful fabrication and characterization of two p-type inverted coaxial point contact HPGe detectors featuring novel thin amorphous-germanium dual-blocking contacts, which demonstrate stable low-leakage operation and high energy resolution while revealing significant geometry-dependent trade-offs in depletion behavior and charge collection.
This paper presents a non-destructive, contactless frequency domain laser ultrasound method utilizing zero-group velocity guided elastic wave resonances to accurately measure the wall thickness of millimeter-sized inertial confinement fusion capsules, with results that align excellently with infrared interferometry references.
This paper presents a novel framework combining high-fidelity Monte Carlo simulations with Bayesian inference to achieve rapid, high-accuracy quantification of mobile gamma-ray sources, significantly advancing capabilities in radiological safety, geophysical mapping, and space exploration.
This study presents the first direct observational evidence that tropospheric winds, independent of temperature inversions, impose azimuth-dependent low-pass filtering on infrasound from controlled explosions at short ranges, causing upwind paths to exhibit systematically longer periods and different celerity compared to downwind paths.
This paper presents facility-wide measurements of the KEK Accelerator Test Facility's Low-Level RF clock phase-noise power spectral density and discusses the resulting synchronization floor imposed by the stability of its Linac and Damping Ring signal generators, which are critical for achieving the ~100 fs-level synchronization required for nanobeam technology testing.
This paper presents the results of a side-by-side intercomparison between semiconductor and scintillator-based gamma imagers to provide guidance on their optimal utilization in a tiered nuclear security and forensic response strategy.
