The course will cover the physics of particle detectors and particle accelerators. It will introduce the experimental techniques used in nuclear, particle physics and photon science, and describe the layout and functionality of modern experiments. History, operating principles of modern particle accelerators and applications in nuclear, sub-nuclear and medical physics will be treated as well.
Through classroom lectures, dedicated seminars held by experts and hands-on exercise sessions, the Detectors and Accelerators in Particle Physics course proposes:
- to deepen the knowledge of the interactions of elementary particles with matter;
- to analyze the functioning of the various detectors used for the detection of elementary particles in nuclear and subnuclear physics;
- to examine some current experiments of greater interest;
- to provide an introduction to the physics of particle accelerators by also presenting future projects;
- to teach how to design and simulate simple experimental using the Geant4 software library.
At the end of the course, students will be familiar with modern detection and particle acceleration methods in particle and applied physics. They will have the basis to understand the motivations and the functioning of the various parts of an experiment in high energy physics or instrumentation for the control of the beams in medical physics laboratories. This will include the ability to size and select detectors suitable for the purposes of the experiments to be examined or to be designed.
They will know how to describe measurements of ionization, position, energy, and momentum of particles, as well as particle identification and timing measurements. They will develop competence in quickly and critically acquiring information from publications other then textbooks.

To pass the exam it is necessary to pass a written test and an home project assigned near the end of the course.
A minimal score of 15/30 is mandatory to pass the written test and a minimal score of 18/30 for the home project.
The final grade will be given by the mean of the score of the written test and the score of the home project, incremented by 5%. Students can decide to accept the proposed vote and register it, or can ask for an additional oral exam (covering full course program) to improve it.
It is necessary to demonstrate to have acquired sufficient knowledge of both concept and applications of the concepts and methods discussed during the course.
To achieve a score of 30/30 cum laude, the student must demonstrate that he has acquired an excellent knowledge of the topics covered in the course, and to be able to master the software tools needed to develop and implement simulation of simple detector setups with Geant4.
The determination of the final grade takes into account the following elements:
1. written test 50%
It is an individual test in which the student solve simple exercises on particle interaction with matter, particle detectors, particle accelerators.
The evaluation will take into account:
- the correctness of the concepts presented;
- clarity and rigor in the discussion of the in-depth presentation;
- reasoning ability on the clarification of the questions;
- the student's aptitudes to understand the choice of detectors with regard to their characteristics and the phenomena to be observed.
2. Home project 50%
The project will be dimensioned in such a way that it requires a maximum of 1 week of work to be completed and documented (a written report of maximum 10 pages + code and dataset is required to reproduce the results reported in the report). It will consist in implementing with Geant4 a simple detector simulation setup.
The evaluation will take into account:
- Correctness of the concepts exposed;
- Clarity of presentation;
- Ability to elaborate the concepts learned in the development of original projects;
- Ability to use the Geant4 software library to solve the given problem.
