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 …

A setup to investigate fields of magnetic quadrupole lenses was designed and constructed. It
allows the spatial position of the axis and the multipole structure of the field of a lens (or …

Earlier we have proposed the idea in optics of one-stage quadrupole probe-forming systems
that consisted in using independent power supplies for all lenses [1]. The new arrangement …

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 …

Separated probe-forming systems can be applied to enhance the resolution of a scanning
nuclear microprobe with a comparatively large working distance to accommodate the …

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 …

A probe-forming system based on a separate orthomorphic quadruplet of magnetic
quadrupole lenses with a short working distance is considered, allowing the system …

Justified the search of new probe systems to forming MeV energy proton beams in high
resolution lithographic techniques. To produce description of the nuclear scanning …

This paper describes the performance of probe-forming systems based on a new type of
magnetic quadrupole lens with a conical aperture (MQL CA). The main difference in the …
