5. Conclusion

The purpose of this work was to study a repeatable target production and methods of their noncontact delivery in accordance with the scope of MM-IFE program. Various physics and technology problems accompanying IFE targetfueling development were considered, and approaches to their solution were proposed and experimentally tested partially. Our thermal, mechanical, and levitation modeling (theoretical and experimental) are important tools in planning future experiments on MM-IFE and studying IFE reactor fueling.

A particular interest from scientific and technological points of view in IFE progress deals with a cryogenic target that could be delivered to the center of reaction chamber at significant rates. Therefore, our study is devoted to the IFE target fabrication with focusing on methods, which provide a high rep-rate and cost-effective target production. The top-level requirements necessary to achieve successful target fabrication and injection deal with target material selecting and fuel layer structuring. The following issues are of key importance:

1. For target mass-production those are:

	- Minimization of time and space for all production steps.
	- Moving targets cooperate all production steps in the FST transmission line that is considered as a potential solution of passing from one-of-a-kind techniques to about 1 million targets per day.
	- Moving targets are the necessary condition for realizing a repeatable target production at required rates and their noncontact delivery at the laser focus.
	- Layers with inherent survival features (fuel layer structuring—the grain size should be scaled back into the nanometer range).
	- Noncontact delivery system.
	- Multiple target protection methods including: (a) outer protective cryogenic layers, (b) metal coatings of different configurations and compositions, (c) nanocoatings for specific applications, and (d) coinjection of a special protective cover ahead of the target, etc.

For the IFE, all techniques must be integrated into an FST transmission line capable of producing about 1 million targets per day. Therefore, further studies are needed on MM-IFE connected to guide other R&D programs and to predict the behavior of IFE targets during their layering, delivery, and transport through the chamber environment. In addition, the MM-IFE allows reducing the cost of developments because it is intended to test the reactor-scaled technologies and to identify Mechanical Mockup of IFE Reactor Intended for the Development of Cryogenic Target Mass… DOI: http://dx.doi.org/10.5772/intechopen.81518
