This study presents a practical method using acid extraction and ICP-MS to measure U and Th in liquid scintillator at sub-ppq levels with nearly 100% recovery efficiency and a detection limit of 0.2–0.3 ppq, achieved through rigorous cleanliness control and validated by three standard addition techniques.
To meet the ultra-low radioactive contamination requirements of the JUNO detector, the study details the implementation of a large-scale underground cleanroom system that maintains air cleanliness around class 74,000 and introduces a highly sensitive ICP-MS method for directly measuring and controlling U/Th deposition rates on detector surfaces.
This paper establishes a per-pixel optogeometric throughput factor, , to explicitly map scene radiance to incident photon counts at the detector level, thereby defining the fundamental shot-noise-limited signal-to-noise ratio bounds for individual pixels based on optical geometry.
This paper experimentally demonstrates a novel on-axis laser ranging interferometer architecture for future gravity missions, achieving nanometer-accuracy inter-spacecraft measurements with high pointing stability and minimal polarization-induced noise through active beam steering and tilt-to-length coupling mitigation.
This paper outlines recent enhancements to the VOXES Von Hamos spectrometer, including the integration of an energy-dispersive detection line, a liquid-sample holder, and a Y-shaped support for transmission geometry, which collectively expand its capabilities for high-resolution, automated laboratory XES and XAS studies.
This paper presents a radiation-hardened 130 nm CMOS delta-sigma current digitizer capable of achieving over 200 dB dynamic range and sub-picoampere resolution for beam loss monitoring, while maintaining a 10 µs response time for machine protection and demonstrating robust performance up to 100 Mrad total ionizing dose.
This paper presents a novel two-dimensional shift and rotation method that leverages the correlation between time-of-flight mass-squared and ionization energy loss to significantly improve charged pion and kaon identification in heavy-ion collisions, extending the reliable measurement range to approximately 3 GeV/ while maintaining over 98% purity and preserving elliptic flow consistency.
This paper proposes a data-driven "structured generalized sliced Wasserstein distance" method using randomized neural networks to directly analyze two-dimensional polarized images from Gas Pixel Detectors, successfully determining X-ray polarization and incident angles while demonstrating high consistency with traditional statistical models.
This paper presents a novel, low-power, software-based calibration method for gamma-ray detectors that utilizes full-spectrum analysis and Monte-Carlo modeling to maintain stable energy calibration in uncontrolled environments, effectively eliminating the need for active temperature control while decoupling instrumental drift from environmental background fluctuations.
This paper introduces a new, computationally efficient matrix-based algorithm for determining antineutrino directionality in segmented reactor detectors, offering improved accuracy and error analysis over conventional methods while identifying optimal segmentation scales for low-count regimes.
