recent data of extensive air showers recorded by alborz i array and their detailed analysis

An array of five scintillation detectors has been installed in sharif university of technology to record extensive air showers. ‎‎‎by using the time lags of the secondary particles of air showers relative to each other and the location of each of these ‎particles‎ relative to the core of the shower, the arrival direction of the primary particle producing each air shower has been ‎obtained.‎‎‎these data show that the distribution of time intervals of successive events in all directions of arrival into‎ the atmosphere is a random distribution‎. the distribution of the time intervals between successive events in different ‎seasons‎ has also been obtained and the seasonal effect has been ‎investigated‎. the effects of the environment‎, ‎including temperature and pressure‎, on the cosmic ray count rate have been investigated‎. ‎the distribution of zenith and azimuth angles‎, ‎as well as‎ the ‎solar,‎ sidereal, and antisidereal time distributions of cosmic rays‎, ‎have been obtained‎.
