2. 2 How well can we measure the incline tracks? How many micromegas planes do we need to achieve 1 mrad resolution? Use a toy Monte Carlo to study these questions. Parameters of the problem: Number of mm planes, N Distance between planes, L Singe hit resolution, Δx Angle of incline tracks, θ L L θ N=1 N=2 N=3
