Description
This thesis is mainly about the search for exotic heavy particles -Intermediate
Mass Magnetic Monopoles, Nuclearites and Q-balls with the SLIM experiment
at the Chacaltaya High Altitude Laboratory (5230 m, Bolivia), establishing
upper limits (90% CL) in the absence of candidates, which are among the best
if not the only one for all three kind of particles. A preliminary study of the
background induced by cosmic neutron in CR39 at the SLIM site, using Monte
Carlo simulations.
The measurement of the elemental abundance of the primary cosmic ray
with the CAKE experiment on board of a stratospherical balloon; the charge
distribution obtained spans in the range 5≤Z≤31.
Both experiments were based on the use of plastic Nuclear Track Detectors,
which records the passage of ionizing particles; by using some chemical reagents
such passage can be make visible at optical microscopes.
