Radiation interaction with matter
Master PhysiqueParcours Subatomic and Astroparticle Physics
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.
