Abstract

AbstractWe study the correlations between charged particles in small cosmic ray air showers and determine the size and nature of their density fluctuations. We have used the CORSIKA simulation program to investigate this question. The result obtained shows the “intermittent” behaviour of the individual realisations of the density distributions. This is interesting in itself, and the specific values of the scaled factorial moments allow us to estimate the possible effects of these large non-Poissonian fluctuations. These may be relevant in the analysis of data from small shower arrays and other atypical measurement situations where cosmic ray particles provide an unwanted background.
