摘要: 欧洲核子中心的大型强子对撞机探测器预计工作在 1 0 34 /(cm2·s)亮度 ,这将导致实验大厅的本底非常严重 .薄气隙室将作为 ATLAS实验中的前端 μ子触发器 .按照模拟计算 ,实验大厅薄气隙室周围的主要本底是中子和光子 .报告了薄气隙室探测器的 γ灵敏度的实验测量 .使用 γ能量从20ke V到1.8Me V的放射性 γ源 .目前测量的灵敏度小于 1 % ,与用 EGS4模拟计算结果相吻合. The Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN) is expected to operate at the luminosity of 10 34 /(cm 2 ·s), and the resulting background condition in the experimental hall would be quit severe. Thin Gap Chamber (TGC) will be used for forward muon triggering in the ATLAS experiment. According to a simulation, the main source of the background around TGC in the experimental hall is neutrons and photons. The sensitivity measurement for TGC...Abstract: The Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN) is expected to operate at the luminosity of 10 34 /(cm 2 ·s), and the resulting background condition in the experimental hall would be quit severe.
