In this research project, I have carried out research and development of new calibration system aiming for reduction in systematic uncertainty and improvement of sensitivity in next generation neutrino oscillation experiments.With the new calibration system, light from laser is fed into detector through optical fiber and distributed inside the detector via diffuser ball. The diffuser ball can be moved inside the detector by the wire operation, and therefore we can proceed detector calibration in parallel to the regular data taking.A small prototype calibration system was build during this research project. Using the prototype system, it was demonstrated that the system works as designed. This can be considered as a milestone to implement the new calibration system in the future experiment.

在本研究项目中，为了降低下一代中微子振荡实验中的系统不确定度，提高实验灵敏度，我进行了新的定标系统的研究和开发。新的定标系统将激光器发出的光通过光纤送入探测器，并通过扩散球在探测器内部进行分配。通过有线操作，扩散球可以在探测器内部移动，因此可以在常规数据采集的同时进行探测器标定。使用原型系统，它是证明了系统的工作原理。这可以被认为是一个里程碑，以实现新的校准系统在未来的实验。
