Learning objective
Understand how a charged particle's energy is spent on ionising and exciting atoms.
Analyse how the Bethe–Bloch formula depends on the particle's charge and velocity and on the medium.
Learn to calculate ranges of heavy particles and electrons with empirical formulas.
Know the radiative losses of electrons, Cherenkov radiation and the exponential attenuation of gamma rays.
Expected outcomes
Can estimate specific ionisation losses and explain the shape of the Bragg curve.
Can calculate ranges of alpha particles and electrons in air, water and aluminium.
Can find the number of ion pairs produced and the critical energy.
Can calculate the Cherenkov threshold and the half-value layer for gamma radiation.
