Spin rotation and deflection of high energy charged particles in a bent crystal due to multiple scattering by atomic strings

“…In these articles they used "channeling" for what had earlier been called hyperchanneling and "abovebarrier" to refer to the channeling region in the vicinity of the critical angle. A review article by Akhiezer et al 26 and an article by Greenenko and Shul'ga 30 herald the later work.…”

While information exists on high energy negative particle channeling there has been little study of the challenges of negative particle bending and channeling collimation. Partly this is because negative dechanneling lengths are relatively much shorter. Electrons are not particularly useful for investigating negative particle channeling effects because their material interactions are dominated by channeling radiation. Another important factor is that the current central challenge in channeling collimation is the proton-proton Large Hadron Collider (LHC) where both beams are positive. On the other hand in the future the collimation question might reemerge for electron-positron or muon colliders. Dechanneling lengths increase at higher energies so that part of the negative particle experimental challenge diminishes. In the article different approaches to determining negative dechanneling lengths are reviewed. The more complicated case for axial channeling is also discussed. Muon channeling as a tool to investigate dechanneling is also discussed. While it is now possible to study muon channeling it will probably not illuminate the study of negative dechanneling.
