The beam optics in a nuclear microprobe is considered on the basis of quality criteria for
focusing systems. In this consideration, empirical criteria with dominant chromatic or intrinsic …

We apply the phase field crystal method for nonequilibrium patterning to stochastic systems
with an external source in which transient dynamics is essential. Considering a prototype …

Among different configurations of lens systems for nuclear microprobes, the most common
one is a triplet of magnetic quadrupole lenses. Nowadays, microanalysis and material …

We consider the processes of pattern selection in a class of nonequilibrium binary stochastic
systems subjected to an external influence. A possibility for the process of pattern selection …

The present work was undertaken to improve the parameters of existing nuclear
microprobes based on a triplet lens system by transforming them into quintuplet. In such a …

In order to expand applications of the Lanzhou microbeam the resent improvements were
introduced in its slits, lens system and target chamber. In this study a beam optics of the new …

The paper describes a study of the ion beam formation for irradiation of microareas of
construction materials with individual grains. A numerical simulation of the microbeam …

The new Sumy nuclear microprobe for high resolution applications has the same beam line
with the present microprobe and uses the same object and aperture collimators. The new …

The paper reports the research trends in developing probe-forming systems with high
demagnification and analysis factors that limit a nuclear microprobe resolution. Parasitic …

The work describes nonlinear processes of probe formation on the target with allowance for
an inhomogeneous density of ion distribution in phase space in the object collimator plane …
