Abstract

On the hypothesis that the highest-energy cosmic rays consist at least in part of magnetic monopoles, heavily ionizing particles have been sought at ground level using an 18-m2 detector array exposed for 630 days. The observable flux of Dirac monopoles at ground level is less than 1.5 × 10−9/m2 sec sr with 95% confidence. Monopoles are not the dominant cause of air showers having energies up to 3.0 × 1016 eV.
