🧲 Calorimeter Shower: Depth, Containment and Energy Resolution (2D)

Side view of an electromagnetic calorimeter with the energy deposited layer by layer shown in colour and shower particles drifting through it. Set the beam energy, the particle type, the radiation length and critical energy of the material, the detector depth and the stochastic and constant terms of the resolution, and see where the shower peaks, how deep it must be to contain 95 per cent, how much leaks out and the resulting resolution. The profile normalisation, the shower maximum, the containment and the resolution are checked numerically, with four in-page numerical checks.
