Abstract

The SLIM experiment was a large array of nuclear track detectors located at the Chacaltaya high altitude Laboratory (5230 m a.s.l.). The detector was in particular sensitive to intermediate mass magnetic monopoles, with masses 10⁵ GeV <M_M< 10¹² GeV. From the analysis of the full detector exposed for more than 4 years a flux upper limit of 1.3×10^-15 cm^-2 s^-1 sr^-1 for downgoing fast intermediate mass monopoles was established at the 90% C.L.
