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.

本研究的目的是：·设计和测试几种类型的中微子束线上初级质子和次级粒子探测器的基本特性·开发和建立一种快速提取初级质子束的监测和调谐系统的方法，以实现有效的（中微子）束输运。设计并测试了CT（电流互感器）、SPIC（分段板离子室）、SEC（二次发射室）和GC（气体切伦科夫）等几种类型的探测器。这些探测器安装在目前的主质子束流线上，用于长基线中微子振荡实验。编制了探测器信号的数据采集程序，建立了波束控制程序。1999年6月19日下午6点42分，由于超级神冈探测器的KEK中微子束，第一个中微子事件被观测到。这是第一次证明人工制造的粒子在地球上穿越了250公里。该研究为实现难以探测到的、沿250 km距离飞行的中微子的高效束流输运发挥了关键作用。
