30TeV以上的伽马射线源探测是寻找银河系宇宙射线源的一种令人鼓舞的方法。使用大视场探测器对伽马射线源进行全天探测对于100GeV以上的各种类型的源的人口积累是必不可少的。为了实现这些目标，在海拔4300英里处建造了1公里(2)的大型空气簇射粒子探测器阵列(LHAASO项目)。是提议的。133，按照建议在阵列中增加两个MagicII型望远镜，LHAASO将增强源形态调查能力。建议的阵列还将用于测量超过30TeV的单个宇宙线物种的能谱。通过将广视场望远镜重新配置为荧光探测器阵列，探测器阵列的孔径可以扩大到覆盖第二膝关节所在的100PeV以上的能区。为了将能量尺度转移到超高能宇宙线实验中，将测量宇宙线的光谱和成分。
Gamma ray source detection above 30 TeV is an encouraging approach for finding galactic cosmic ray sources. All sky survey for gamma ray sources using Wide field of view detector is essential for population accumulation for various types of sources above 100 GeV. In order to target those goals, a, large air shower particle detector array of 1 km(2) (the LHAASO project) at 4300 m a.s.l. is proposed. 133, adding two MagicII-type telescopes in the array as proposed, LHAASO will be enhanced in source morphologic investigation power. The proposed array will be utilized also for energy spectrum measurement for individual cosmic ray species above 30 TeV. By re-configuring the wide field of view telescopes into fluorescence light detector array, the aperture of the detector array can be enlarged to cover an energy region above 100 PeV where the second knee is located. Cosmic ray spectrum and composition will be measured in order to transfer an energy scale to ultra high energy cosmic ray experiments.
