Ultrafast near-infrared pyroelectric detector based on inhomogeneous plasmonic metasurface

Light: Science & Applications
Pyroelectric (PE) detection technologies have attracted extensive attention due to the cooling-free, bias-free, and broadband properties. However, the PE signals are generated by the continuous energy conversion processes from light, heat, to electricity,

New constraint on dark photon at T2K off-axis near detector

Journal of High Energy Physics, 2023
The T2K experiment is one of the most powerful long-baseline experiments to investigate neutrino oscillations. The off-axis near detector called ND280 is installed 280 m downstream from the neutrino production target to measure the neutrino energy ...

Mass hierarchy sensitivity of medium baseline reactor neutrino experiments with multiple detectors

Nuclear Physics B, 2017
We report the neutrino mass hierarchy (MH) determination of medium baseline reactor neutrino experiments with multiple detectors, where the sensitivity of measuring the MH can be significantly improved by adding a near detector.

Hard X-ray full-field nanoimaging using a direct photon-counting detector

Journal of Synchrotron Radiation, 2023
Full-field X-ray nanoimaging is a widely used tool in a broad range of scientific areas. In particular, for low-absorbing biological or medical samples, phase contrast methods have to be considered.

Cosmic Ray Background Removal With Deep Neural Networks in SBND

Frontiers in Artificial Intelligence, 2021
In liquid argon time projection chambers exposed to neutrino beams and running on or near surface levels, cosmic muons, and other cosmic particles are incident on the detectors while a single neutrino-induced event is being recorded.
