On Earth we are constantly bombarded by elementary particles produced when cosmic rays interact in the atmosphere. The cosmic rays are produced in a wealth of different sources, from our own Sun to violent astrophysical events such as supernovae. At their highest energies they far exceed any energies achieved in man-made accelerators such as the LHC at CERN.
The talk will describe cosmic rays, their sources and the innovative experiments devised to study them. The presentation will then go onto discuss how the cosmic rays detected on earth can be used as a tool to study disparate subjects such as monitoring carbon capture and storage and looking for nuclear contraband in cargo containers.
