Study on some mechanism of plane shadow production at a shifted source

The paper deals with the mechanism of formation of plane shadow at a shifted source through which deepening affects the form of plane shodow, particularly, through periodical pumping of channeled particle flux in the space transverse momentum space resulting from the particle reflection from the channel walls. Considered is a simple model when the particle flux escaping from the shifted source moves in the region of the harmonical potential of the plane. Particles with the transverse kinetic energy less than the potential barrier, are reflected from the walls and entrained into the channeling inside the plane channel
