The Theory of Volume Capture by a Curved Crystal in the Channeling Regime

The idea1 of the possible deflection of high-energy particles channeling in a bent single crystal2 has attracted great interest because of the potential application of this effect for beam control. Initial reports of successful attempts to use bent crystals as a septum for proton beam extraction from accelerators at energies 8.4 GeV3 and 800 GeV4 have already been published.
