Description
In recent years, a few groups have reported detections of gamma rays in the 100 TeV region from astronomical objects in the galaxy using extensive air shower arrays.
These observations have certainly taken a new step in the research of cosmic-ray acceleration mechanisms.
Several spread TeV gamma-ray sources have been observed in the galaxy.
To study the acceleration mechanisms, it is important to investigate a correlation between gamma-ray source and molecular cloud and to identify the exact gamma-ray emission region.
In extensive air shower experiments, an arrival direction of a cosmic ray is determined by estimating the shape of its air shower front based on a detected secondary particle density distribution and detection time.
Here, we report a study on shapes of water Cherenkov detector to determine arrival directions of air showers with good accuracy.
