This paper demonstrates that a portable, two-meter neutron Time of Flight system utilizing Neutron Resonance Transmission Analysis can successfully identify and quantify the isotopic composition of special nuclear materials like HEU and reactor-grade plutonium within two hours with high accuracy, offering a promising tool for future arms control verification.
This paper reports on the development of a high-speed, high-resolution X-ray camera based on the INTPIX4NA SOIPIX detector and a SiTCP-XG 10GbE readout system, demonstrating its successful application in three recent experiments at KEK facilities: X-ray zooming microscopy, phase-contrast imaging, and nondestructive lithium detection in battery materials.
This paper presents the design, production, and comprehensive optical characterization of novel light-pulse driver circuits and self-monitoring calibration instruments (both directional pulsers and isotropic P-CAL modules) developed for the Pacific Ocean Neutrino Experiment, demonstrating their high-intensity, nanosecond-scale performance and near-perfect optical isotropy through simulations and experimental validation in air and water.
This paper presents the development of a compact, high-performance readout electronics system based on the Timepix4 chip and a single ZYNQ-MPSOC, designed to meet the high event-rate demands of the Phase II Chinese Spallation Neutron Source by achieving stable 5.12 Gbps data transmission and demonstrating successful X-ray imaging capabilities.
This paper presents CTPX1, a highly integrated, data-driven camera system based on the Timepix4 ASIC that achieves a peak readout rate of 1.17 Ghits/s and stable thermal performance, successfully addressing the saturation challenges of next-generation high-flux neutron imaging instruments like ERNI at the upgraded CSNS-II.
This paper presents a real-time, all-fiber microendoscopic polarization sensor that achieves single-photon-level accuracy and complete state reconstruction in constrained, low-light environments by utilizing a few-mode fiber coupled with a deep-learning-based calibration neural network.
This paper identifies spontaneous athermal phonon bursts originating from the bulk silicon substrate as the dominant source of low-energy background events and excess noise in superconducting sensors, demonstrating that these bursts scale linearly with substrate thickness and relax over time, thereby establishing a critical link to quasiparticle poisoning in superconducting qubits.
