The discovery of the supersymmetry particles is highly expected in LHC-ATLAS experiment. Reconfirmation of the discovery potential with the latest detector simulation framework was conducted. In this study, the special supersymmetry signatures with energetic gamma-rays, or the long lived supersymmetric particles are explored and summarized in the paper. Since 2009.11, the commissioning of the detectors with the real collision data and the detector performance check has been carried out.

在LHC-ATLAS实验中，超对称粒子的发现备受期待。利用最新的探测器模拟框架对发现潜力进行了重新确认。本文对高能伽玛射线的特殊超对称特征或长寿命超对称粒子进行了探索和总结。自2009年9月11日起，利用真实碰撞数据对探测器进行了调试，并对探测器进行了性能检查。
