Objectives of this research are・ To design and test basic characteristics of several types of detectors for primary protons and secondary particles at the neutrino beam line・ To develop and establish a method of the monitoring and tuning system of the fast extracted primary proton beam for the efficient (neutrino) beam transportation.Several types of detectors such as CT (Current Transformer), SPIC (Segmented Plate Ion Chamber), SEC (Secondary Emission Chamber) and GC (Gas Cherenkov) are designed and tested.These detectors are installed and being used at the present primary proton beam line for the long base-line neutrino oscillation experiment.The data acquisition program for detector signals has been developed and the beam control procedure has been established. On June 19, 1999, 6:42 PM, the first neutrino event was observed due to the KEK neutrino beam in the SuperKamiokande detector. This was the first demonstration that a particle that had been produced artificially and traversed 250km in Earth was detected.This research played a key role for the efficient beam transportation of neutrinos which are hardly detected and should fly along the distance of 250 km.

这项研究的目标是设计和测试神经元束系的主要质子和次级颗粒的几种类型的检测器的基本特征。设计和测试Cherenkov。这些探测器已安装并在当前的主要质子束线上用于长基线神经元振荡实验。已开发了检测器信号的数据采集程序，并确定了光束控制程序。 1999年6月19日，下午6:42，由于Superkamiokande检测器中的Kek神经元束，观察到了第一个神经元事件。这是第一次证明，在地球中检测到了人为产生并横穿250公里的粒子。这项研究对于几乎未检测到的神经元的有效束传输起着关键作用，该粒子几乎未被检测到，并应沿着250公里的距离飞行。
