SSLG4: A novel scintillator simulation library for Geant4

This study introduces a new Scintillator Simulation Library called SSLG4 for the Geant4 Monte Carlo simulation package. With SSLG4, we aim to enhance efficiency and accelerate progress in optical simulations within the Geant4 framework by simplifying scintillator handling and providing a rich repository of scintillators. The SSLG4 enables users to quickly include predefined scintillator materials in their simulations without requiring manual definition. The library initially contains 68 scintillators, consisting of 58 organic and 10 inorganic types. Most of these scintillators are selected from the catalogs of several scintillator manufacturers, notably Eljen and Luxium. Other scintillators are included based on their widespread use across various physics domains. The library stores optical data of scintillators in ASCII files with .mac and .txt extensions, enabling users to add, remove, or modify properties of scintillators at runtime of their applications. In addition, we made all the scintillator data available in the library on a dedicated page of our website to ensure convenient access for all users.本研究针对Geant4蒙特卡洛模拟软件包，推出一款全新的闪烁体模拟库SSLG4（Scintillator Simulation Library）。本库旨在通过简化闪烁体（scintillator）处理流程、构建丰富的闪烁体资源库，提升Geant4框架内光学模拟的效率，加速相关研究进程。借助SSLG4，用户无需手动定义即可快速将预定义的闪烁体材料纳入其模拟流程。 该库初始包含68种闪烁体，其中58种为有机闪烁体，10种为无机闪烁体。其中多数闪烁体取自多家闪烁体生产商的产品目录，尤以Eljen与Luxium两家厂商的产品为代表；其余闪烁体则因在多个物理学领域的广泛应用而被纳入库中。 该库将闪烁体的光学数据存储于扩展名为.mac和.txt的ASCII格式文件中，支持用户在应用程序运行阶段对闪烁体的属性进行添加、删除或修改操作。此外，本研究将库内所有闪烁体数据发布于官方网站的专属页面，以保障所有用户均可便捷获取相关资源。
