“…Then angular scans were performed at different cradle angles ( h ) to reach the best possible alignment of the h111i axis with the beam, according to the procedure described in Ref. [14]. Figure 2 shows the beam intensity distributions as a function of the particle deflection in the horizontal ( x ) and vertical directions ( y ) due to the interaction with the crystal at three different values of v .…”

Beam deflection due to axial channeling in a silicon crystal bent along the h111i 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. Such a condition allowed one to observe a beam deflection of 50 rad with about 30% efficiency. The contribution of hyperchanneled states of protons to the observed beam deflection was less than 2% according to simulation results.
