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.
