Learning objectives
Dopo una introduzione sui meccanismi di interazione con la materia di particelle cariche, raggi gamma e neutroni, verranno presentate le proprietà generali dei rivelatori. Veranno inoltre discussi apparati di rivelazione attuali e in fase di costruzione, in collegamento con la realizzazione di esperimenti di frontiera nel campo della fisica nucleare
