Search for superheavy grand unified magnetic monopoles in cosmic rays. Academic Article uri icon


  • A search for superheavy grand unified magnetic monopoles has been performed utilizing a 7.37.3-m2 array of scintillation counters, sited underground at a depth of 1148 hg/cm2. This apparatus measures both the time of flight and specific ionization of particles passing through it and has a trigger which is sensitive to prompt as well as very slowly developing pulses from the detector. No monopole events were observed during 6700 h of live-time operation of this detector, yielding an upper limit on the flux of monopoles of 4.610-14 cm-2sr-1sec-1 (90% confidence level) in the velocity range 8.510-4c to 0.012c. 1987 The American Physical Society.
