Abstract

The FOOT experiment of INFN is devoted to the measurement of the nuclear fragmentation double differential cross sections useful for the improvement of calculation models adopted in hadrontherapy and radioprotection. A detailed Monte Carlo simulation of the FOOT magnetic spectrometer has been implemented in order to optimize the design and to guide data analysis. This task has been accomplished by means of the FLUKA Monte Carlo code. The input files of the FLUKA simulations are created from the software framework of the experiment, in order to have a consistent generation and description of geometry and materials in both simulation and data analysis. In addition, this ensures the possibility of processing both simulated and real data with the same data analysis procedures. Databases containing specific parameters describing the setup employed in each different data taking campaign are used. A customized event-by-event output of the Monte Carlo code has been developed. It can be read out by the general software framework of FOOT, enabling access to the generation history of all particles in the same event. This output structure therefore gives the possibility to perform a detailed analysis and study of all relevant processes, allowing the detailed tracking reconstruction of all individual particles. Examples of results are presented.

FOOT 实验磁谱仪的 FLUKA 蒙特卡洛模拟

INFN 的 FOOT 实验致力于测量核碎裂双差分截面，这对改进放射性治疗和放射防护中采用的计算模型非常有用。为了优化设计和指导数据分析，对 FOOT 磁谱仪进行了详细的蒙特卡罗模拟。这项任务是通过 FLUKA 蒙特卡罗代码完成的。FLUKA 模拟的输入文件是根据实验的软件框架创建的，以便在模拟和数据分析中对几何形状和材料进行一致的生成和描述。此外，这还确保了使用相同的数据分析程序处理模拟数据和真实数据的可能性。数据库中包含描述每个不同数据采集活动所使用的设置的特定参数。蒙地卡罗代码的逐个事件定制输出已经开发出来。它可以由 FOOT 的通用软件框架读出，从而能够访问同一事件中所有粒子的生成历史。因此，这种输出结构提供了对所有相关过程进行详细分析和研究的可能性，允许对所有单个粒子进行详细的跟踪重建。现介绍一些结果实例。

期刊介绍： The focus of CPC is on contemporary computational methods and techniques and their implementation, the effectiveness of which will normally be evidenced by the author(s) within the context of a substantive problem in physics. Within this setting CPC publishes two types of paper. Computer Programs in Physics (CPiP) These papers describe significant computer programs to be archived in the CPC Program Library which is held in the Mendeley Data repository. The submitted software must be covered by an approved open source licence. Papers and associated computer programs that address a problem of contemporary interest in physics that cannot be solved by current software are particularly encouraged. Computational Physics Papers (CP) These are research papers in, but are not limited to, the following themes across computational physics and related disciplines. mathematical and numerical methods and algorithms; computational models including those associated with the design, control and analysis of experiments; and algebraic computation. Each will normally include software implementation and performance details. The software implementation should, ideally, be available via GitHub, Zenodo or an institutional repository.In addition, research papers on the impact of advanced computer architecture and special purpose computers on computing in the physical sciences and software topics related to, and of importance in, the physical sciences may be considered.
