The goal of the course is to illustrate the experimental methods used in particle physics directly involving students in all phases; from the project to the data analysis of small scale experiments using silicon semiconductor telescopes and plastic scintillators.
Expected learning outcomes
The student will acquire the following skills:
1. He will be able to describe how silicon detectors and plastic scintillators works;
2. He will be able to calculate the energy released in a material from a particle at MIP and to determine the half life of the positron;
3. He will be able to build up the acquisition chain for both the experiments; i.d. the energy in the semiconductors and the measurements of time for the determination of the half life of the positronium;
4. He will be able to analyze the data in order to reconstruct the Landau curves and the positronium half life.
Lesson period: First semester
(In case of multiple editions, please check the period, as it may vary)
The laboratory activities deal with the measurement of the half-life of positronium and the reconstruction of the Landau curve in thin silicon detectors.
Prerequisites for admission
1. Basic knowledge of radioactivity and interaction of radiation with matter. 2. Knowledge of typical electronic instruments use in laboratory such as oscilloscopes, pulses generator, amplifiers. 3. Knowledge of silicon detectors and scintillator.
The two experiments will be first explained from a theoretical point of view; than they will be performed in laboratory after to have explained the use of the needed instrumentation.

Assessment methods and Criteria
Students have to present an elaborate of 30-40 pages in groups of three about the topics covered in the laboratory. During the examination students are invited individually to expose the content of the elaborate.
