Basic knowledge of electro-magnetism, quantum physics and programming. Attendance to the course of Laboratory of Nuclear and Sub-Nuclear Physics I is advised.

The course aims to provide in-depth knowledge of some types of detectors, both from the theoretical and the practical point of views, through laboratory experiments.

1) Lectures. Scintillation detectors: general characteristics, re-emission law, organic and inorganic scintillators. Photo-multiplier tube (PMT): general characteristics, photocathode, window, focusing, multiplication, gain, dividers, pulse shape, time response, energy resolution, dark current. Other photo-detection devices: photodiodes, APD, Silicon PM.
2) Laboratory. Characterization of two XP2020 PMTs: dark current, gain measurement and noise inter-times. Study of the distribution of cosmic rays as a function of zenith angle. Measurement of the life-time of the muon at rest.
