This paper presents the design, architecture, and successful validation of the continuous, triggerless data acquisition system for the DarkSide-20k dark matter experiment, which utilizes custom FPGA firmware and a distributed processing farm to achieve high-efficiency, background-free WIMP searches with unprecedented sensitivity.
This paper presents a novel monolithic plastic scintillator tracker concept utilizing embedded scatterers and wavelength-shifting fiber readout, which was experimentally validated via a positron beam test to achieve near-100% detection efficiency and sub-pitch position resolution (1.47 mm at normal incidence).
This paper presents improvements to the Cosmic Explorer Location Search (CELS) code and the integration of astrophysical requirements to evaluate and identify promising sites in the United States for the 40km Cosmic Explorer gravitational-wave observatory, focusing on minimizing construction costs related to geology, geography, and topography.
This paper reports that beam tests on thin, carbon-co-implanted Low-Gain Avalanche Diodes (LGADs) at DESY achieved a single-sensor timing resolution of 16.6 ps for 20 µm-thick devices and maintained a 20 ps resolution even after irradiation to high neutron fluences at cryogenic temperatures.
This paper presents a comprehensive characterization of 7-pad resistive PICOSEC Micromegas detector prototypes at CERN, demonstrating that a 10MΩ resistive layer configuration achieves optimal stability and robustness while maintaining exceptional timing (22.9 ps) and spatial (1.19 mm) resolutions, thereby validating resistive technology for scalable, high-performance gaseous timing detectors.
This paper reports a novel experiment demonstrating that applying a helical magnetic field at the "Magic Angle" of 54.7° induces a permanent ferromagnetic state in room-temperature DPPH, significantly increasing its magnetic permeability by aligning unpaired electron spins.
The paper proposes the ITACA apparatus, which enhances gas xenon time projection chambers for neutrinoless double-beta decay searches by introducing trace ammonia to create slow-drifting ammonium ions, enabling high-resolution ion-track imaging that complements electron tracking to significantly improve background rejection through superior topological discrimination.
This paper presents a new angular-resolved reflectance measurement system operating in a gaseous argon atmosphere that characterizes aluminum and stainless steel materials relevant to DUNE, revealing significantly lower vacuum ultraviolet reflectance (10–15%) compared to UV-VIS values and providing critical data for optimizing future noble gas detector simulations.
The paper introduces JetPrism, a configurable Conditional Flow Matching framework that addresses the misleading nature of standard training losses in nuclear physics simulations by establishing a multi-metric evaluation protocol to ensure generative models achieve true physical fidelity and convergence beyond generic loss indicators.
This paper presents a focused-ion-beam-assisted electrostatic transfer method for precisely attaching prefabricated sub-micron magnetic particles to microcantilevers, enabling the creation of custom magnetic tips with minimal fabrication damage and broad applicability for scanning probe microscopy.
