CERN/ALICE是欧洲核子中心的大型强子对撞机上唯一进行超高能重离子碰撞实验的大科学工程,其物理目标是探索夸克-胶子等离子体QGP,或称夸克物质,了解QCD禁闭和本征对称性破缺恢复机理。中国参加ALICE主要任务是参与光子谱仪量能器探测装置（PHOS）的建造、测试与安装。光子谱仪（PHOS）是由17920个钨酸铅晶体组成的探测器点阵系统。中国原子能科学研究院承担的前期工作之一是开发研制由大面积PIN紫光灵敏硅二极管和微型电荷灵
CERN / ALICE is the only large science project on the LHC at the Nuclear Center of the European Union that aims to explore quark-gluon plasma QGPs, or quarks, to understand QCD confinement and this Symmetry breaking recovery mechanism. The main task of participating in ALICE in China is to participate in the construction, testing and installation of the photon spectrometer measuring device (PHOS). Photon Spectrometer (PHOS) is composed of 17920 lead tungstate crystal lattice detector system. China Institute of Atomic Energy to undertake one of the preparatory work is to develop a large area by the PIN purple light sensitive silicon diodes and micro-charge
