摘要

Abstract

The dependence of the focal length of the thallium Tl⁺ ion beam on the parameters of the ion-optical system of the injector for diagnostics of plasma by heavy ion beam probe has been studied. The possibility of obtaining quasi-parallel beams and converging beams with a focal length of more than 4 m has been shown. Experimental results are compared with the results of computer modeling of the beam trajectory in the injector.
