Project summary

Project has the task to develop an ion beam energy recuperator theoretically and experimentally and the engineering fundamentals for designing similar systems. The usage of the recuperator can turn out to be a noticeable contribution into design of injectors for the future ecologically-pure fusion energy production technique. The equipment of the facilities for electromagnetic isotope separation with similar devices will allow one to make the isotopes used in medicine cheaper.

The studies on the proposed Project have applied nature, being in complete agreement with the ISTC goals.

The main directions in realization of Project are the following: detailed calculation-based theoretical description of operating processes in the recuperator; experimental study of recuperator characteristics, their comparison with calculations and development of fundamentals for designing similar systems.

Development of a numerical recuperator model will include the following stages: physical and mathematical statement of the problem, option of a technique for its solution, development and debugging of codes realizing the chosen technique; study of various design modifications and that of various approaches to organization of an operating process.

The experimental recuperator study will include the following stages: option of a technique for studies and the facility equipment with necessary instrumentation, along with this, the design and manufacture of the first recuperator modification with which the technique, separate elements of the recuperator design will be developed and the preliminary results will be obtained. On the basis of these results, using the data from a numerical analysis, the final design modification will be developed, the technique will be precised and the main volume of experimental studies will be realized. When this work will be completed, its results will be published and the solution on the expediency of its continuation will be adopted.

The engineering essence of the proposal is in the displacement of electron sources within the recuperator, in the vicinity to the collector electrode. Such a modification allows one to produce, a plasma configuration consisting of the beam ions and emitter electrons in the collector zone. The boundary of this configuration, being mobile, will be automatically adjusted to the ion beam parameters. Thus one can increase the density of an ion current passing through the recuperator and reduce the energy losses in the process of recuperation. Some estimates show that the energy losses can be reduce from (25-30)% to (3-5)%, i.e. 5-10 times.
