Simulation Study on the Performance of Synchronized Compact Arrays within 1 Km Baseline
Abstract
The synchronized compact arrays for detecting extensive air shower (EAS) are deployed in Okayama, Japan, as part of the Large Area Air Shower (LAAS) experiments. 4 arrays in Okayama area are indep endently operated and equipp ed with the precise GPS system, of which time resolution is 1 µs. The baselines of 4 arrays range from 100m to 1000m. We analyzed time interval distributions of EASs between each array. Event pairs in time interval less than 1 µs were observed, ant the number of them are much more than that expected by chance coincidence. Observing energy ranges were estimated for these events by CORSIKA simutaion codes. By using simultaneous observed EAS at multiple synchronized arrays, we can select higher energy EAS effectively.
