(54) LENGTH LASER SOURCE OF DEUTERONS

 . ...

The invention relates to a technique for producing plasma ion sources, and more specifically to targets for laser sources of deuterons.

Targets for laernetic deuteron sources are known, consisting of substrates on which a layer of a metal that dissolves hydrogen, deposited on deuterium l, is deposited.

The study of such CI targets showed that, along with high emitting fission, they have low stability, sometimes reaching 50%. For crocuta, the effect of the first laser pulse on the Li O target often did not lead to the appearance of deuterons in the laser bunch due to the presence of an oxide film formed as a result of the interaction of the target with the atmosphere.

Also known is a target for a laser source of deuterons 12 containing a substrate with a deutero-containing film deposited on it.

It is a podpozhku, on which a layer of titanium or zirconium, Nsi "for 4 deuterium. Such a target has a stability several times better than a target of L i D, but at the same time, the emission of deuteron & in from it is 4-5 times less. In addition to TOfo, this Myshen has a small resource.

The aim of the invention is to increase the emission of deuterons with a target when exposed to laser radiation, as well as an increase in target resources.

The goal is achieved by

That the film is made in the form of a sequence of the highest series of eOei from lithium deuteride and hydrogen dissolving metal deuteride.

Its surface is

5 alternating protrusions and projections.

The angle at the top of the protrusion or depression lies in the range from 1 to 90.

The drawing shows the proposed target section.

The target consists of three mutually. Reduction of lithium deuteride layers of: a metal that dissolves hydrogen, such as titanium: TiO-1, LfD-2 and 5 of the substrate 3.

The target works as follows.

On the target surface, which is a sequence of binary layers, with the surface layer
