Muon-Induced X-ray Emission (MIXE) [1-4] is a non-destructive analytical technique that leverages negative muons to probe elemental and isotopic compositions by detecting characteristic muonic X-rays emitted during atomic cascades and gamma rays from nuclear capture processes. By controlling the muon beam momentum, MIXE enables depth-resolved analysis, spanning microns to centimeters, making...
Cosmic ray muon imaging, as a non-invasive imaging modality, utilizes naturally occurring cosmic ray muons as penetrating probes to reconstruct the distribution of matter. A critical challenge in designing position-sensitive muon detectors lies in optimizing the trade-off among three key parameters: detection area, spatial resolution, and manufacturing cost. Owing to their proven feasibility...
The muEDM experiment at the Paul Scherrer Institut (PSI) aims to measure the muon electric dipole moment (EDM) with unprecedented sensitivity, targeting σ(dμ)=6×10−23 e·cm, a three-order-of-magnitude improvement over the current limit established by the BNL muon g−2 experiment. Central to this effort is the muon trigger detector (TrigDet), positioned at the solenoid entrance,...
我们提出了一个新颖的暗物质探索实验:DREAMuS(利用先进缪子源研究暗物质),使用位于中国的强流重离子加速器装置(HIAF)提供的GeV级缪子束流开展暗物质研究。DREAMuS实验旨在搜寻一种与缪子有特定耦合的暗物质粒子,这类粒子通过带味破坏的重型Z玻色子进行相互作用。该实验将寻找含轻子味破坏的标准模型新物理,并为包括缪子反常磁矩在内的多种实验反常现象提供解释。实验信号特征表现为高横动量的电子,并伴随来自中微子与暗物质粒子的大缺失能量。
本报告将介绍DREAMuS实验的理论框架、模拟研究及预期探测灵敏度,突出其通过缪子相互作用研究暗物质及相关新物理现象的潜力。
Generating a mono-energetic, high-energy muon beam using accelerator facilities can be very attractive for many purposes, for example, searching for muon related new physics beyond the Standard Model. One potential accelerator facility is the High Intensity Heavy-Ion Accelerator Facility (HIAF), which is currently under construction in Huizhou City, China. Considering the projectile energy and...
The Muon g-2 Experiment at Fermilab measures the anomalous part of the muon magnetic dipole moment, a_{\mu}, and searches for a non-zero muon electric dipole moment (EDM). Both are excellent probes of new physics; precise measurements of a_{\mu} can help disentangle current tensions in the Standard Model (SM) prediction, and the predicted muon EDM is beyond current experimental reach. An EDM...
A detailed simulation and 3D reconstruction of copper and skull are presented in this talk. Imaging performance is compared to that of Xrays tomography.
