The mean lateral density distribution of muons in extensive air showers detected at Haverah Park

Abstract

Presents the results and conclusions from an experiment carried out between 1969 and 1973 at the Haverah Park cosmic ray extensive air shower detector array near Harrogate, Yorkshire. The detector consisted of 12m2 of shielded neon flash tubes sensitive to muons of energy greater than 300 sec theta MeV. The detector was situated at the centre of the EAS array and its response to showers of primary energy 1017 eV<or approximately=Ep<or approximately=1019 eV, with zenith angles up to 60 degrees has been studied. The analysis has been restricted to those showers in which the distance (R) from the core of the shower to the detector was in the interval 100<R<1000 m. The results are compared with model calculations and a number of conclusions drawn.
