摘要:

在为X射线望远镜的背景研究开发了BoGEMMS(博洛尼亚Geant 4多任务模拟器)模板之后,为伽马射线空间任务(例如AGILE,Fermi)的模拟建立了一个新的扩展,设想作为当前和未来电子跟踪伽马射线空间望远镜的通用多用途框架。伽马射线扩展涉及Geant 4质量模型,物理列表,更重要的是,模拟输出的产生和处理。从用户的角度来看,模拟设置遵循树形结构,主要级别是选择模拟框架(一般,X射线或伽马射线应用),次要级别是几何结构和输出格式的详细配置。BoGEMMS在伽马射线飞行任务中的应用已被用于评估新一代伽马射线望远镜(如伽马光望远镜)的仪器性能,目前正在对AGILE飞行任务进行全面模拟,以便用真实的空间数据集对模拟器进行科学验证和校准。这里给出了BoGEMMS伽马射线框架的完整描述,并概述了当前和未来实验的潜在应用所取得的结果(例如,伽马-400和伽马光)。的光子转换效率的β粒子对的评价和比较列表数据允许的初步物理验证的整体架构。将用于研究Gamma-Light仪器性能的伽马射线模块应用报告为参考测试用例。

英文摘要:

After the development of a BoGEMMS (Bologna Geant4 Multi-Mission Simulator) template for the back- ground study of X-ray telescopes, a new extension is built for the simulation of a Gamma-ray space mission (e.g. AGILE, Fermi), conceived to work as a common, multi-purpose framework for the present and future electron tracking gamma-ray space telescopes. The Gamma-ray extension involves the Geant4 mass model, the physics list and, more important, the production and treatment of the simulation output. From the user point of view, the simulation set-up follows a tree structure, with the main level being the selection of the simulation framework (the general, X-ray or gamma-ray application) and the secondary levels being the detailed configuration of the geometry and the output format. The BoGEMMS application to Gamma-ray missions has been used to evaluate the instrument performances of a new generation of Gamma-ray tele- scopes (e.g. Gamma-Light), and a full simulation of the AGILE mission is currently under construction, to scientifically validate and calibrate the simulator with real in-space data sets. A complete description of the BoGEMMS Gamma-ray framework is presented here, with an overview of the achieved results for the potential application to present and future experiments (e.g., GAMMA-400 and Gamma-Light). The evaluation of the photon conversion efficiency to beta particle pairs and the comparison to tabulated data allows the preliminary physical validation of the overall architecture. The Gamma-ray module application for the study of the Gamma-Light instrument performances is reported as reference test case.
