Air Shower Events of High-Energy Cosmic Rays Measured at the North Side of Seoul

초록

COREA collaboration have installed an array of three detetor stations in Hansung Science High School for the measurement of air-shower events from high-energy cosmic rays. Each station consists of four plastic scintillation detectos covering the area 2 x 2 m^2. Coincidence signals from any two detectors in a station are recorded as single-station events, together with absolute GPS time information of the events. Air-shower events have been successfully selected using the time difference of station events. The preliminary results of the data analysis is presented.
