Focusing techniques

Definition

Focusing techniques refer to methods used in particle accelerators to direct and confine beams of charged particles, enhancing their intensity and precision for research purposes. These techniques are essential for achieving high luminosity, which allows researchers to conduct experiments that require precise interactions between particles. By optimizing the shape and direction of the beam, focusing techniques ensure that particles collide effectively, thereby maximizing the data obtained from experiments.
