Objectives of this research are・To investigate basic characteristics(light yields, attenuation length) of several scintillating fiber samples, and design a prototype of a live scintillating fiber block detector for a scattering experiment・To develop and establish a method of the pattern recognition for image data of hyperon scatterings obtained from a scintillating fiber detectorPhoton yields and attenuation lengths for several fiber samples were measured by using a beta-source. A fiber block detector was designed and assembled.As for the pattern recognition (automatic tracking and particle identification), a computer code was developed by comparing results of recognition by human-eyes. The efficiencies for all the processes were evaluated with Monte Carlo simulation by feeding simulated image data to the same analysis precedure as the one for the real data.A method of the automatic tracking for image data of hyperon production obtained from a scintillating fiber detector has established.

这项研究的目的是研究几个闪烁的纤维样品的基本特征（光线产量，衰减长度），并设计一个实时闪烁的纤维块探测器的原型，用于散射实验・开发和建立一种通过闪烁纤维探测器散射的图像数据的模式识别的方法，并建立了镜头探测器量的图像数据的方法，并建立了衰减量的图像数据，并建立一种方法。 beta源。设计并组装了纤维块检测器。作为模式识别（自动跟踪和粒子识别），通过比较人眼的识别结果来开发计算机代码。通过将模拟图像数据馈送到与真实数据相同的分析之前，用蒙特卡洛模拟评估了所有过程的效率。自动跟踪的方法是从闪烁的光纤探测器获得的超子产生的图像数据的方法。
