Study of a scintillating fiber detector for a scattering experiment

Objectives of this research To design and test basic characteristics of several typedetectors for primary protons and secondary particles at the neutrino beam line To develop andestablish a method of the monitoring and tuning system of the fast extracted主要proton beam forthe efficient (neutrino) beam transportation.Several types of detectors such as CTTransformer), SPIC （Segmented Plate Ion Chamber）SEC (Secondary Emission Chamber) and GC (Gas Cherenkov) are designed and tested.These detectors areinstalled and being used at the present primary proton beam line for the long base-line neutrinooscillation experiment.The data acquisition program for detector signals has been developed and thebeam 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 traversed250km in Earth was detected.This research played a key role for the efficient beam transportation ofneutrinos which are hardly detected， should fly along the distance of 250公里。
