The Haverah Park extensive air shower array

Abstract

The experimental facilities offered by the Haverah Park extensive air shower array are described. This array contains four deep Cerenkov detectors, each of area 34 m2, spaced 500 m apart. The response of the detectors to the different components of the cosmic radiation are described and the performance of the array as a whole is considered. The array is efficient in detecting showers from primary particles having energies in the range 1017-1018 ev and responds efficiently to showers arriving at large zenith angles.
