摘要

欧洲核子研究中心的ATLAS实验模拟程序目前处于完全运行模式,并集成到ATLAS的通用分析框架ATHENA中。在DC2数据挑战期间使用的基于GEANT4的OO方法已经在ATHENA内部使用LCG字典和Python脚本与GEANT4进行了接口。在DC2数据挑战中证明了该应用程序的鲁棒性。Python界面增加了模拟工具所需的灵活性、模块化和交互性,以一种通用的方式处理不同的完整ATLAS模拟设置、测试光束和宇宙射线研究。进行了生成、仿真和数字化步骤,以进行性能和鲁棒性测试。在ATLAS联合测试束(2004年)和正在进行的宇宙射线研究的背景下,与真实数据的比较已经成为可能

ATLAS detector simulation: status and outlook
The simulation program for the ATLAS experiment at CERN is currently in a full operational mode and integrated into the ATLAS's common analysis framework, ATHENA. The OO approach, based on GEANT4, and in use during the DC2 data challenge has been interfaced within ATHENA and to GEANT4 using the LCG dictionaries and Python scripting. The robustness of the application was proved during the DC2 data challenge. The Python interface has added the flexibility, modularity and interactivity that the simulation tool needs to tackle, in a common way, different full ATLAS simulations setups, test beams and cosmic ray studies. Generation, simulation and digitization steps were exercised for performance and robustness tests. The comparison with real data has been possible in the context of the ATLAS combined test beam (2004) and ongoing cosmic ray studies
