DATA ANALYSIS TECHNIQUES FOR NUCLEAR AND PARTICLE PHYSICSAcademic Year 2022/2023 - Teacher: Giuseppe POLITI
Expected Learning Outcomes
Providing a good level of knowledge in the field of particle detectors used in nuclear and particle physics with the related electronics and data acquisition systems.
Developing capabilities to use autonomously this instrumentation in order to mount different typical experimental set up of nuclear and subnuclear physics with various techniques, with related data aquisition and following analysis
Increasing critical and judgment skills thanks to the indipendent realization of laboratory experiment requiring a continuous facing of practical experimental problems
Developping communication skill thanks to the presentation of the driven experiment and of the obtained results in a written report, and of acquired knowledge in an oral exam.
Pushing to an indipendent prosecution of studying by stimulating the research on the course items that are in continuous evolution due to the research in the field.
Classes on theoretical parts (3CFU) 21 hours
Experimental sessions in laboratory with increasing degree of autonomy (3CFU) 45 hours
