Crystals with small thickness along the beam exhibit top performance for steering particle beams through planar channeling. For such crystals, the effect of nuclear dechanneling plays an important role because it affects their efficiency. [...]

We studied the dechanneling length of 150 GeV/c@p^- interacting with a short bent silicon crystal. Dechanneling length measures the rate and the strength of incoherent interactions of channeled particles in a crystal. [...]

Under coherent interactions, particles undergo correlated collisions with the crystal lattice and their motion result in confinement in the fields of atomic planes, i.e. particle channeling. [...]

Observation of nuclear dechanneling length reduction for high energy protons in a short bent crystal

Deflection of 400 GeV/ c protons by a short bent silicon crystal was studied at the CERN SPS. It was shown that the dechanneling probability increases while the dechanneling length decreases with an increase of incident angles of particles relative to the crystal planes. [...]

(Insubria U., Como ; INFN, Milan Bicocca) ; Camattari, R. (Ferrara U. ; INFN, Ferrara) ; De Salvador, D. (INFN, Padua ; Padua U.) et al.
We measured a considerable increase of the emitted radiation by 120 GeV/c electrons in an axially oriented lead tungstate scintillator crystal, if compared to the case in which the sample was not aligned with the beam direction. This enhancement resulted from the interaction of particles with the strong crystalline electromagnetic field. [...]

Beam deflection due to axial channeling in a silicon crystal bent along the [111] axis was observed with 400 GeV/c protons at the CERN Super Proton Synchrotron. The condition for doughnut scattering of protons by the atomic strings of the crystal was attained. [...]

Observation of multiple volume reflection by different planes in one bent silicon crystal for high-energy negative particles

Multiple volume reflection by different planes passing through the < 111 > axis in a bent silicon crystal was observed for the first time for 150 GeV/c negative particles, pi(-) mesons, at one of the secondary beams of the CERN SPS. The beam of pi(-) mesons was deflected opposite to the crystal bend by an angle of about 48 mu rad, which is 4.6 times larger than in a single volume reflection by the (110) bent planes [...]
