Cosmic-rays Física Experimental de Partículas com Aceleradores
Planet Earth is constantly being struck by cosmic rays — particles expelled by distant stars and galaxies. These messengers from outer space bring much information about the history and composition of the Universe. Cosmic ray physics is an active field of research, with many ongoing experiments addressing questions on their origin, nature, acceleration and propagation. The very wide range of energies of cosmic rays implies that different detection methods are used, from complex space-based experiments to ground-based giant air shower detectors. The LIP cosmic ray group covers much of this range and has excellent conditions to play a leading role in R&D for future detectors.
