If aligned with the crystal planes within a certain angle (Critical Angle), an impinging particle can be trapped by the inter-planar potential, following a path constrained by the minima of this potential. This effect is known as Channeling. If the crystal is bent, the particle will follow the crystal plane bending.
Nowadays it is possible to exploit the coherent interaction of particles in crystals in order to perform beam extraction, collimation and merging (coalescence).
The aim of this presentation is to introduce crystal-assisted beam manipulation in particle accelerators, focusing to the actual state-of-the-art applications and further developments of this techniques.
