1 Particle Detection 1. Costituents of Matter 2. Fundamental Forces
4. Symmetries and Conservation Laws 5. Relativistic Kinematics 6. The Quark Model 7. The Weak Interaction 8. Introduction to the Standard Model

2 What do we require in a particle detector ?

3 Different information can be obtained by different techniques

4

5 Energy loss by ionization and excitation on the electrons of the material

6 This is the usual calculation leading to the Bethe-Bloch formula for the energy loss of a (heavy) charged particle in the bulk of a material

7 Must be supplemented by quantum mechanical considerations

8 The final formula

9

10 Energy loss for a heavy charged particle (heavier than the electron) in Copper

11 Radiation mechanism has to be added at very high energy
This process will dominate above a «critical» energy

12

13

14 Energy loss across all the energy board

15

16 Development of an electromagnetic shower

17

19 Cerenkov imaging

20 Threshold matching method

22 Particle Detector Systems make use of several integrated detector units

23 The part of the CDF detector at Femilab which is dedicated to muon detection

24 The CDF detector at Femilab

25 Focus detector at Femilab: a fixed target multiparticle spectrometer

26 Superkamiokande detector in the Kamioka Mine: a huge water-Cerenkov detector to search for neutrino interactions and other rare events

27 Superkamiokande detector in the Kamioka Mine

28 An interferometer scheme for gravitational wave detections

29 Inside the Virgo detector: the mirrors
Inside the Virgo detector: the vacuum tunnel
