| Research Abstract |
We have developed trigger system dedicated to measurement of high energy cosmic ray. Interaction of high energy cosmic rays causes cascade showers. The shape of cascade showers depends on the particle type and energy of cosmic rays. Such feature can be used for particle discrimination. In order to investigate the shower trigger system for particle discrimination, we developed prototype detectors and calculated particle interaction in the detectors with the Monte-Carlo simulation. Analyzing data of detector response obtained from accelerator experiments, we evaluated the performance of the shower trigger system.
