2004年，在ATLAS(环状大型强子对撞机)联合测试束上，ATLAS筒状探测器的一片(包括内部探测器设置和液体Ar量热计)暴露于欧洲核子研究中心H8 SPS束流线上的粒子。这是第一次测试ATLAS的组合电子性能。本文给出了在20GeV/c~100GeV/c的磁场作用下，用内探测器测量动量p和用拉尔量热计进行电子测量(能量、线性度和分辨率)的结果。此外，还讨论了跃迁辐射跟踪器的粒子识别能力、依赖拉尔量热计的韧致辐射恢复算法、E/p比的结果和标度参数的提取方法。
In 2004 at the ATLAS (A Toroidal LHC ApparatuS) combined test beam, one slice of the ATLAS barrel detector (including an Inner Detector set-up and the Liquid Argon calorimeter) was exposed to particles from the H8 SPS beam line at CERN. It was the first occasion to test the combined electron performance of ATLAS. This paper presents results obtained for the momentum measurement p with the Inner Detector and for the performance of the electron measurement with the LAr calorimeter (energy E linearity and resolution) in the presence of a magnetic field in the Inner Detector for momenta ranging from 20 GeV/c to 100 GeV/c. Furthermore the particle identification capabilities of the Transition Radiation Tracker, Bremsstrahlungs-recovery algorithms relying on the LAr calorimeter and results obtained for the E/p ratio and a way how to extract scale parameters will be discussed.
