Radiation and spin separation of high energy positrons channeled in bent crystals

Channeling and Radiation in Periodically Bent Crystals

“…2. It was shown in [51], that in the case of planar channeling the crystal bending noticeably affects the spectrum only if the condition Θ c γ ≤ 1 is met the features of ChR if L c ∝ λ (here, L c = R/γ is the formation (coherence) length of the radiation emitted from an arc of the circle of the radius R), but becomes of the quasi-synchrotron type in the opposite limit [51,271]. The latter motion gives rise to the synchrotron-type radiation, i.e.…”

“…Right bottom a Si 1−x Ge x superlattice crystalline undulator with four periods. 3) used in recent channeling experiments [50][51][52]. Hansen, A. Nylandsted and U. Uggerhøj (University of Aarhus)) strong that they are able to steer the particles much more effectively than even the most advanced superconductive magnets.…”

“…The phenomenon of ChR of a charged projectile in a linear crystal, see e.g. non-periodic, one-arc) bent channel [21,22,51,137,255,272,273], are known, e + e - non-periodic, one-arc) bent channel [21,22,51,137,255,272,273], are known, e + e -…”

“…To conclude this section we mention that various aspects of radiation formed in crystals bent with the constant curvature radius R were discussed in [21,22,51,137,255,272,273] although with various degree of detail.…”
