“…Simulations show that values of b around 20 m at the crystal position are optimal at the SPS [77]. 4. A virtue of the extraction of particles by means of a bent crystal is that the corresponding septum thickness is equivalent to the inecient surface layer which can be made as small as 10 nm.…”

“…In the seventies, investigations at high energies began [26] and, with them, the application of channeling to the steering of beams. That novel use of bent crystals was proposed by Tsyganov in 1976 [27] and observed few years later [28,29]. Beam extraction through crystals was later investigated at IHEP [30], CERN [31] and Fermilab [32] where a beam extraction efficiency of 20-30% was reached.…”

“…There are three main mechanisms of beam deflection by a bent crystal. The first one is planar channeling, which was predicted in [2,3] and experimentally observed in [4]. In this mechanism, charged particles are captured by the field of bent atomic a e-mail: igor.kirillin@gmail.com planes and thereby deflected by an angle equal to the angle of crystal bend.…”

Influence of incoherent scattering on stochastic deflection of high-energy negative particle beams in bent crystals

An investigation on stochastic deflection of highenergy negatively charged particles in a bent crystal was carried out. On the basis of analytical calculation and numerical simulation it was shown that there is a maximum angle at which most of the beam is deflected. The existence of a maximum, which is taken in the correspondence of the optimal radius of curvature, is a novelty with respect to the case of positively charged particles, for which the deflection angle can be freely increased by increasing the crystal length. This difference has to be ascribed to the stronger contribution of incoherent scattering affecting the dynamics of negative particles that move closer to atomic nuclei and electrons. We therefore identified the ideal parameters for the exploitation of axial confinement for negatively charged particle beam manipulation in future high-energy accelerators, e.g., ILC or muon colliders.
