The course presents the state-of-art of particle accelerators presently in operation, describing their main features and the most important physical laws and technological limitations defining their performances.
The course is mainly devoted to the students interested in particle physics on accelerators, but can, in the final part, focus more on the medical and technical applications of these machines, according to the students preferences. The primal goal is giving all the needed information to understand the capabilities and the limitations of accelerating machines.
The various types of accelerators will be described to the students, along with the main features of the beams that every machine can deliver. The technological and physically intrinsic limitations of each typology will be analysed in detail, thus allowing the students to fully understand how the particle physics experiment are interfaced with the accelerators and how the particles beams are produced for medical purposes, material analyses, and other tasks. The main goal of the course is getting the best comprehension of the features characterising the accelerated beams, such as emittance, dispersion, luminosity and others, and the technological choices that allow for these results.
Electromagnetism
Principles of special relativity
Principles of nuclear and subnuclear physics
The course is based on lectures (48 hours) normally held by the teacher. For selected topics, after an agreement with the students, it will be possible for them to be requested to prepare short presentations, which will be considered as a bonus for the final exam.

All class schedules are posted on the EasyAcademy portal.
The final exam will be an interview of the student on the whole course content. Facultatively the students will be allowed to prepare a short presentation on a selected topic, designed in agreement with the teacher.
The student will face an oral exam covering the whole content of the course.
