Abstract :
This paper is devoted to the theoretical study of the influence of the space charge on broadening of the protons beam of a nuclear microprobe. The nonrelativistic proton beam, having energy about 1 MeV is investigated. The paraxial beam characterized by small radius and small slope angles of trajectories is considered. The change of the mechanical trajectory of the proton in the radial direction evoked by the spatial charge distributed in some conical volume according to the assigned law is also considered.
