宇宙线缪子 缪子多模态成像 图像质量
2022/3/23
缪子多模态成像有效利用了宇宙线缪子与材料相互作用产生的散射信息以及产生次级诱发中子的缪子信息。为对缪子多模态成像图像质量进行分析,基于GEANT4程序设置了探测模型,从缪子多重库仑散射模块和缪子诱发中子模块两部分对探测模型可靠性进行了验证,开发了缪子多模态成像模拟程序,得到了重建图像。成像12h可达到4mm的空间分辨率,成像时间在小时量级可清晰分辨边长10cm的235U立方体和其他常见的高、中、低...

2011/7/21
The energy dependence of charged-hadron production in proton-proton collisions at RHIC and LHC energies is investigated in a nonequilibrium-statistical relativistic diffusion model (RDM) with three so...
Electromagnetic signatures of a strongly coupled anisotropic plasma
anisotropic plasma strongly coupled
2011/7/21
In heavy-ion collisions, quark-gluon plasma is likely to be produced with sizable initial pressure anisotropy, which may leave an imprint on electromagnetic observables.
