详细描述了紧凑的蒙特卡罗模拟代码“G3sim”，用于研究具有波长移位器 (WLS) 光纤读数的塑料闪烁体探测器的性能。 G3sim 是为了优化 GRAPES-3 广泛空气喷淋实验中使用的新型闪烁体探测器的设计而开发的。通过吸收、全内反射和漫反射来处理相对论性带电粒子在闪烁体中通过所产生的蓝色光子的传播。 WLS 光纤捕获蓝色光子并随后重新发射较长波长的绿色光子进行适当处理。 WLS 光纤内绿色光子的捕获和传播使用子午和斜射光线的光学定律进行处理。在光电倍增器处生成电信号时考虑每个光子的传播时间。将 G3sim 的结果与原型闪烁体探测器的性能进行比较，结果表明模拟和测量的特性非常一致。模拟结果可以根据指数函数进行参数化，从而更深入地了解这些多功能探测器的功能。 G3sim 可用于在实际制造之前帮助设计和优化闪烁体探测器的性能，这可能会节省大量时间、劳动力和金钱。
A detailed description of a compact Monte Carlo simulation code "G3sim" for studying the performance of a plastic scintillator detector with wavelength shifter (WLS) fiber readout is presented. G3sim was developed for optimizing the design of new scintillator detectors used in the GRAPES-3 extensive air shower experiment. Propagation of the blue photons produced by the passage of relativistic charged particles in the scintillator is treated by incorporating the absorption, total internal, and diffuse reflections. Capture of blue photons by the WLS fibers and subsequent re-emission of longer wavelength green photons is appropriately treated. The trapping and propagation of green photons inside the WLS fiber is treated using the laws of optics for meridional and skew rays. Propagation time of each photon is taken into account for the generation of the electrical signal at the photomultiplier. A comparison of the results from G3sim with the performance of a prototype scintillator detector showed an excellent agreement between the simulated and measured properties. The simulation results can be parametrized in terms of exponential functions providing a deeper insight into the functioning of these versatile detectors. G3sim can be used to aid the design and optimize the performance of scintillator detectors prior to actual fabrication that may result in a considerable saving of time, labor, and money spent.
