CODE 98891 ACADEMIC YEAR 2018/2019 CREDITS 6 cfu anno 2 FISICA 9012 (LM-17) - GENOVA 6 cfu anno 1 FISICA 9012 (LM-17) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR FIS/01 TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB AIMS AND CONTENT LEARNING OUTCOMES The course will teach the basics of the “physics of detectors for particles and radiation” as well as their application. The physical mechanisms by which particles (or radiation) create signals in detectors will be explained in detail as well as the effects of electrode structuring on resolution. Applications of different detector types mostly in particle physics experiments, but also in photo detectors, and for biomedical imaging will be presented. AIMS AND LEARNING OUTCOMES Students will receive a detailed education on detectors, their physics and their operation principle, signal generation (weighting field), sources of noise and how to tune for optimal obtainable resolution. The lecture starts with how radiation is “seen” in a detetctor, what physics processes are responsible. How does an electrical signal (and noise) develop? How is charge in a detector transported? Which are the benefits, advantages and disadvantages of different detector types? What is Cherenkov and transition radiation? How do they differ? How can detectors exploit these radiations? How do scintillation detectors work and what is the underlying phayis? Particle tracking and particle identification will be explained. How to measure energy in calorimeters? What are the obtainable resolutions (in space and energy) and how can they be optimized? Some details about readout techniques will also be covered. TEACHING METHODS Lectures at the blackboard with support for powerpoint presentations SYLLABUS/CONTENT Interactions of particles/radiation with matter (cross section, mean free path, energy loss) Transport of charges in matter (drift and diffusion) Signal generation on electrodes in detectors Ionization detectors (gas-filled detectors and semiconductor detectors) Photodetectors Cherenkov Detectors Transition Radiation Detectors Scintillation Detectors Calorimeters (Electromagnetic Calorimeters and Hadron Calorimeters) And if time allows ...

It concerns the home work subject plus another subject taught in the course. The written exam (if applied) will have 15 questions/little exercises to solve during a duration of 2 hours.
