Investigation of rechanneling and dynamic equilibrium effects in crystals

Channeling of high-energy particles in bent crystals – Experiments at the CERN SPS

“…In a similar fashion one can derive the reverse of the curvature dechanneling, the so-called gradient volume capture [26,36,37]. As the particle is incident on a centrifugally distorted planar potential for which the shape changes towards a nondistorted potential (when the curvature diminishes in the direction of motion), a particle can get caught if it enters within DE 9 pvkx djadz above the lower potential barrier.…”

“…Volume capture is quite small in Si already at 70 GeV, w 70 9 0X08% R [m], see [26,36]. Nevertheless, volume capture can be used to measure (bending-) dechanneling lengths in materials in which it is not possible to select channeled particles by means of energy-loss discrimination.…”
