Collimation

Definition

Collimation refers to the process of aligning and directing a beam of particles or light into a parallel or focused arrangement. In the context of particle acceleration, collimation is crucial for ensuring that accelerated particles maintain their intended trajectories, which enhances the precision of experimental results and optimizes the interaction between particles and their targets.
