A highly collimated beam of protons (<InlineEquation ID="Equ1"> <EquationSource Format="TEX">$\approx$</EquationSource> </InlineEquation>1 MeV) entering the channel of a monocrystal film forms at a certain depth an extremely sharp (0.005 nm) and relatively long (some monolayers of the crystal) focusing area where the increase of the flux density can reach thousand times. Impinging...</equationsource></inlineequation>
