Learning Objectives

The course aims to give students an in-depth knowledge of all the principles of Physics on which he particle accelerators is based and to demonstrate in detail the technology that makes these machines possible. The applications of accelerators in other research fields different from nuclear and particle physics will also be shown. Particular attention will be given to medical applications and for this will be given the physical knowledge related to the interaction of radiation with matter.Knowledge and understanding (knowledge and understanding). Critical understanding of the main concepts underlying the dynamics of the motion of beams of electrons and ions in circular and lineal accelerators. Understanding of the methods of deduction of the fundamental physical mechanisms involved beautiful application of electron beams, photons and ions in applications in the medical field. Ability to apply knowledge and understanding Ability to identify the essential elements of phenomena related to particle acceleration and their production, in terms of order of size and level of approximation needed, and be able to make approximations requests. Ability to use the analogy tool to apply solutions known in the field of the interaction particles-electromagnetic fields and of the physics of the plasmas to new problems (problem solving) and different contexts of nuclear physics and its applications to medicine. Communication skills (communication skills). Communication skills in particle accelerators, plasma physics and applications to medicine Learning skills. Acquisition of adequate cognitive tools for the continuous updating of the knowledge and the ability to access specialized literature in the field of accelerator physics, plasmas and aviation techniques based on particle accelerators (Radiology, Nuclear Medicine and Oncology Radiotherapy) and in the field of clinical dosimetry.
