In this work, the simulation of optical photons is carried out in an antineutrino detector module consisting of a plastic scintillator connected to light guides and photomultipliers on both ends, which is considered to be used for remote reactor monitoring in the field of nuclear safety. Using Monte Carlo (MC) based GEANT4 simulation, numerous parameters influencing the light collection and thereby the energy resolution of the antineutrino detector module are studied: e.g., degrees of scintillator surface roughness, reflector type, and its ap- plying method onto scintillator and light guide surface, the reflectivity of the reflector, light guide geometries and diameter of the photocathode. The impact of each parameter is inves- tigated by looking at the detected spectrum, i.e. the number photoelectrons per depositing energy. In addition, the average light collection efficiency of the detector module and its spatial variation are calculated for each simulation setup. According to the simulation re- sults, it is found that photocathode size, light guide shape, reflectivity of reflecting material and wrapping method show a significant impact on the light collection efficiency while scin- tillator surface polishing level and the choose of reflector type show relatively less impact. This study demonstrates that these parameters are very important in the design of plastic scintillator included antineutrino detectors to improve the energy resolution efficiency.

DANSS: Detector of the reactor AntiNeutrino based on Solid Scintillator
DANSS项目旨在创建一个相对紧凑的中微子光谱仪，该光谱仪不包含任何易燃或其他危险液体，因此可能非常接近工业动力反应堆的核心。因此，预计高中微子通量将在灵敏体积为1 m $^3$的探测器中每天提供约15，000次IBD相互作用。塑料闪烁体的高度分割将允许将背景抑制到1%的水平。在Kalinin NPP的3 GW $_{th}$反应堆下使用简化的试验原型DANSSino进行的大量试验证明了所选设计的可操作性。被复合屏蔽包围的DANSS探测器可以通过特殊的起重装置移动，在10 m到12 m的范围内改变与反应堆堆芯的距离。由于这一特性，它不仅可以用于反应堆监测，而且还可以用于基础研究，包括短程中微子振荡到无菌状态。假设一年的测量，预计对振荡参数的灵敏度达到约0.005的水平，其中$sin^2(2θ)$ eV $^2$。
