KNOWLEDGE AND UNDERSTANDING:
Students must have an in-depth understanding of the basic concepts and the most important theories of neutron diffusion and design of components of neutron beam lines and related experimental problems. The verification of knowledge and understanding is done through hands on and oral tests.
APPLYING KNOWLEDGE AND UNDERSTANDING:
Students must be able to identify the essential elements of an even complex neutron diffusion experiment, be able to model it and propose experimental solutions to make it happen. Students must be able to adapt existing models to new experimental data.
COMMUNICATION SKILLS: Students must be able to communicate their knowledge acquired during the course in a clear, correct and unambiguous way. Students must be able to work in an interdisciplinary group and present their research or the results of a bibliographic search to an audience of both specialists and non-specialists. This aspect will be promoted by dedicating 10-15 minutes of each lesson to the revision, and to the possible clarification, of the concepts acquired during the previous lesson and stimulating the students to participate in a class discussion.
LEARNING SKILLS: The student must have acquired adequate skills for the further development and deepening of skills in the area of neutron diffusion and instrumentation through consultation of databases and available scientific literature. Students must be able to tackle new fields through independent study. They must acquire the ability to continue their studies in a research doctorate and / or specialization schools and / or at work. The assessment of learning ability is evaluated during lessons and during oral exams.
AUTONOMY OF JUDGMENT:
Students must be able to independently perform experiments, calculations or numerical simulations. Develop the ability to perform bibliographic searches and to select interesting materials, in particular on the WEB. They must be able to take responsibility for both project planning and facility management. Having achieved an adequate level of ethical awareness in research and in professional activities. These skills are acquired during the study for the preparation of the exams, deepening some specific topics also with the consultation of articles in journals.
