目前GeV到TeV能区已发现众多γ源，多数符合高能电子起源，下一步要找到与高能宇宙线起源密切联系的高能爆发天体。2014年西藏ASγ实验完成了重大升级并开始取数:1)增建4500 m2地下muon探测器，排除宇宙线背景达99.99%，是10TeV以上能区国际最灵敏的γ天文望远镜;2)建成由124台簇射“芯”探测器组成的阵列实验，使百TeV能区，核种分辨率为90%以上，能量决定精度达12%，是目前膝区宇宙线成分能谱观测最灵敏的实验。我们预期可能观测到10-100TeV能区10个左右γ源，也可能观测到未知γ源，将率先实现膝区宇宙线天体物理起源的确定。在宇宙线成分研究方面，将率先观测到质子谱，氦谱及铁谱，测出它们能谱“膝”位置，回答膝区鼓包是否由太阳系邻近的SNR源产生，为宇宙线天体物理起源作出领先的、重要的贡献。

So far，many GeV-TeV γ-ray sources have been found and showed that most are consistent with the origin of high energy electrons. The next duty is to search for high energy bodies that tightly related with the origin of high energy cosmic rays. In 2014 an important upgrade of the Tibet ASγ project was completed. We built: 1. a new underground muon detector with an area of 4500m2 for that a 99.99% background exclusion rate is reached that makes the new ASγ a most sensitive >10TeV γ-ray telescope; 2. a new AS core detection array containing 124 detectors, reaching >90% resolution of nuclear kinds and 12% accuracy of energy determination, that also makes ASγ a most sensitive experiment of the ‘knee’ energy cosmic ray component-spectra observation. Data taking is going on. We expect to observe about 10 γ-ray sources at 10-100TeV region that possibly include unknown sources and give the first evidence of astrophysical origin of ‘knee’ energy cosmic rays. In addition, we expect to firstly obtain the primary proton, helium and iron spectra and their knee positions that will answer whether the peak at the ‘knee’ comes from the SNR sources near the solar system and make a leading and important contribution to the astrophysical origin of ‘knee’ energy cosmic rays.
