A conceptual design of a MeV-energy ion microprobe with an immersion probe-forming system

Abstract

The authors propose a new design for a MeV-energy ion microprobe based on the immersion probe-forming system that employs the accelerating tube at an early stage of beam focusing. The final probing beam formation on the target is provided by a separated Russian quadruplet of magnetic quadrupole lenses. As follows from the calculations, the length of this setup along the beamline (from the ion source to the target) does not exceed 4 m, but the resolution may be higher than that of most operating facilities of conventional design.
