This paper presents a novel, fast, and precise technique for measuring spurious charge in multiple-amplifier sensing charge-coupled devices (MAS-CCDs) by utilizing covariance analysis of output amplifiers, thereby overcoming the limitations of existing empirical methods and enabling reliable large-scale sensor characterization.
This paper proposes a method to predict the positions of all photomultiplier tubes in the JUNO detector based on limited survey data of its deformed structure, demonstrating that incorporating this realistic geometry into reconstruction models eliminates significant vertex biases while confirming that the physical deformation itself has a negligible impact on energy resolution.
This paper presents a validated framework for generating realistic virtual mirror maps by combining Zernike decomposition and spatial frequency analysis with metrology data from Advanced Virgo, enabling systematic optical simulations to assess surface quality specifications for the future Einstein Telescope.
This study demonstrates that charged particles directly produce a significant amount of light (up to 23% relative to scintillating fibers) in wavelength-shifting fibers, a phenomenon previously ignored but now shown to be critical for accurate advanced detector simulations.
This paper presents the calibration methods and monitoring strategies developed to ensure the stable operation of the ALICE ITS2, the largest-scale application of Monolithic Active Pixel Sensors (MAPS) at the LHC, which comprises 24,120 sensors and 12.6 billion pixels.
This study presents the development and characterization of a compact, portable, and efficient X-ray imaging system based on a Raspberry Pi camera and scintillation screens, which achieves clinical-grade spatial resolution and demonstrates versatility across different scintillator materials for scientific, educational, and medical applications.
This paper presents the design and comprehensive analysis of a low-cost, scalable, 20-pair dual-polarized Yagi-UHF/VHF phased array ground station with a pseudo-random layout, evaluating its multi-beamforming, electronic steering, and spectral performance against uniform distributions.
This paper demonstrates that Parnassus, a generative AI model originally developed for LHC experiments, can successfully simulate and reconstruct data for the historical ALEPH detector at LEP, offering a viable solution for legacy data analysis where traditional software is difficult to maintain.
This paper presents a validated comprehensive purity evolution model that incorporates non-uniform impurity transport mechanisms to project the purification performance for the upcoming RELICS-10 and RELICS-50 dual-phase liquid xenon detectors designed to search for reactor-induced coherent elastic neutrino-nucleus scattering.
