| Outline of Final Research Achievements |
We have developed new radiation detectors for high energy charged particles. Our detectors consist of thin inorganic scintillator, Wave Length Shifting Fibers and small photodetectors called SiPM. The pecliarities of our detectors copaired from the standard drift chambers are good position resolution (0.3mm to 0.1mm), low cost (1/2) and thin width (500mm to 1mm). In the case few ten layers of our detectors are mounted, the positon that the high energy gamma-rays convert to rlrctron positron pairs can be measured. The electromagnetic shower detectors measured the center position of the shower. The position resosulion of them are typically 10mm. Our detectors measure the track of primaly electrons and positrons and the vertex positions of the incident gamma-rays convert the e+e- pairs can be calculated. expected position resolution is
less than 0.1 mm.
