  • Nuclear Physics
CONT

Radiation characteristics. Electromagnetic Cascade. The electron and positron beams at SLAC [campus] (up to 50 GeV) are extremely relativistic (the beam energy now is about 100,000 times the electron rest energy), so when an electron interacts in a target material, an electromagnetic cascade develops.

Domaine(s)
  • Physique radiologique et applications
  • Physique nucléaire
CONT

Les particules chargées apparaissent suite aux processus d'interaction nucléaire ou atomique : particules alpha et bêta des processus radioactifs, électron de recul de l'effet Compton ou paire électron-positron issue de la matérialisation des gamma. Ces phénomènes donnent naissance à ce que l'on appelle la cascade électromagnétique qui est une sorte de propagation en arborescence d'électrons, de positrons et de gamma.
