Sliding Interaction of Accelerated Proton Beams with Curved Dielectric Surface

The work is aimed at continuing the study of the “guiding” effect in various aspects. Due to this effect, it is possible to organize contactless transmission of beams of accelerated charged particles along a dielectric surface. In particular, when interacting with a dielectric plate, the guiding effect ensures the transmission of proton beams without ionization energy losses. An experiment was carried out on the sliding interaction of accelerated proton beams with a curved dielectric wall, in which proton beams were pressed against the wall surface by an external electric field. For beams that experienced such an interaction, the energy spectrum was measured. Comparison of the energy spectra of the initial beam and the beam that passed in a sliding mode along a curved dielectric wall showed that in this interaction, as well as when sliding along a flat dielectric wall, proton beams do not experience ionization energy losses.
