Аннотация: It has been studied the process of charged particle transmission through nanoporous
alumina membranes with a pore diameter of about 20 and 200 nm. Experiments with
irradiation were carried out on the AN_2500 accelerator complex. It was shown that
membranes based on nanoporous alumina provide transporting functions to the high-flow
helium ions with energies of 1.5-2 MeV. It has been shown than it is possible to realize spatial
localization of ion impacts on a substrate with a nanoscale resolution.
