Study of a scintillating fiber detector for a scattering experiment

本研究的目标是：·要设计和测试用于初级质子和次级粒子探测器的若干类型的基本特征·要开发和建立用于高效提取初级质子束的监测和调谐系统的方法。（Neutrino）光束运输：探测器的几种类型（CT）（当前变压器）， SPIC（一个分割的盘子离子室）SEC（二次排放室）和GC（Gas Cherenkov）是设计和测试的，这些探测器是安装和使用的，用于当前的主要质子束线--线路中性振荡实验：探测器信号的数据采集程序已经开发出来，波束控制程序已经稳定。1999年6月19日，下午6时42分，第一次中微子活动被观测到KEK中微子光束在SuperKamiokande探测器上。这是第一个演示，它是在地球上生产的250公里的人造和穿越的粒子。这一研究为中微子运输有效的光束发挥了关键作用，该光束几乎被检测到，应该沿着250公里的距离飞行。

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.
