Radiation interaction with matter

Description

This lecture covers the basis of interaction of particles with matter.

It provides the core knowledge needed for lectures about detectors in subatomic physics.

A] Charged radiations :
===============
Heavy charged particles :
-- Bethe Bloch Formula.
-- Multiple Coulomb scattering.

Electrons & Positrons:
-- Bremsstrahlung.
-- Cerenkov effect.

High energy processes:
-- Electromagnetic and hadronic showers.
-- Jets.

B] Neutral radiations :
===============

Photon interaction with matter:
-- Photon scattering : Thomson. Rayleigh. Compton.
-- Photon absorption : Photo-electric effect. Pair-creation.
-- Linear attenuation coefficients from a microscopic approach.

Neutron interactions with matter :
-- Classifications of neutrons and nomenclature.
-- Reactions overview : Elastic and Inelastic Scattering. Absorption reactions.
-- Elastic scattering : Kinematics. Energy moderation, Lethargy.
-- Useful quantities : Mean free path. Transport mean free path.
-- Neutron reaction cross-section analysis : Phenomenological study.
