Calibration of the JEM-EUSO detector
In order to unveil the mystery of ultra high energy cosmic rays (UHECRs), JEM-EUSO (Extreme Universe Space Observatory on-board Japan Experiment Module) will observe extensive air showers induced by UHECRs from the International Space Station orbit with a huge acceptance. Calibration of the JEM-EUSO...
