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.
AIMS AND CONTENT
The course presents the state of the art of particle accelerators currently in use, describing their main characteristics and the main physical laws and technological limitations that determine their performance.
AIMS AND LEARNING OUTCOMES
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.
At the end of the lectures, the student will have the skills to properly identify and recognise the most important accelerators, with the best comprehension of the features of each type: the sudent will also be able to identify the most important parameters of each accelerator and its components, correlating them to the achievable beams with the machines themselves.
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.

TEACHERS AND EXAM BOARD
ANDREA BERSANI (President)
MATTEO DE GERONE (President Substitute)
L'orario di tutti gli insegnamenti è consultabile all'indirizzo EasyAcademy.
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: the exam will be an oral interview, and the student will have the possibility to present an essay on an argument related to the matter of the lectures. Some examples of the possible arguments, not exaustive, could be: specific accelerators, existing or planned, accelerators for specific tasks (energy, arts, medicine...), accelerator components (magnets, cavities, specific beam lines...)
