The direct conversion to electrical energy of the energy carried by the leakage plasma from a fusion reactor and by the ions that are not converted to neutrals in a neutral-beam injector is discussed. The conversion process is electrostatic deceleration and direct particle collection as distinct from plasma expansion against a time-varying magnetic field or conversion in an EXB duct (both MHD). Relatively simple 1-stage plasma direct converters are discussed which can have efficiencies of about 50 percent. More complex and costly (measured in $/kW) 2-, 3-, 4-, and 22-stage concepts have been tested at efficiencies approaching 90 percent. Beam direct converters have been tested at 15 keV and 2 kW of power at 70 +- 2 percent efficiency, and a test of a 120-keV, 1-MW version is being prepared. Designs for a 120-keV, 4-MW unit are presented. The beam direct converter, besides saving on power supplies and on beam dumps, should raise the efficiency of creating a neutral beam from 40 percent without direct conversion to 70 percent with direct conversion for a 120-keV deuterium beam. The technological limits determining power handling and lifetime such as space-charge effects, heat removal, electrode material, sputtering, blistering, voltage holding, and insulation design, are discussed. The application of plasma direct converters to toroidal plasma confinement concepts is also discussed.

Driven Magnetic Fusion Reactors is a collection of papers from the Proceedings of the Course held in Erice-Trapani, Italy on September 18-26, 1978. This collection describes the reactor aspects, the devices, physics, and the common technologies of the ""mirrors"" and the ""two component Tokamaks"" approach. This book reviews the mirror approach, which is used in the magnetic fusion energy program in the U.S. This program focuses on the tandem mirror and field reversed mirror concepts. This book explains the physics of field reversed mirrors and the mirror fusion test facility. The mirror machine as capable of producing fusion reaction with many advantages compared to the mainline tokamak is also discussed. The text also describes other ways to construct a fusion reactor by using a small quantity of quadrupole minimum-B mirrors that are linked toroidally to form a closed-line containment system. This book then presents methods of operating a driven tokamak reactor using the beam heated tokamak BHT, the two-component TCT, and the hot ion tokamak. This collection also describes the roles of low-Q fusion devices, and that of the fission-fusion hybrid version. This text addresses the non-electrical applications of the fusion process that is being done in the U.S. Then this collection also discusses a global approach to the fuel cycles and the different energy strategies of the U.S., Europe, and Japan. This book addresses the many interests of nuclear physicists, nuclear engineers, scientists, students, and academicians in the field of advanced physics.

In principle, the energy released by a fission can be converted directly into electricity by using the charged fission fragments. The first theoretical treatment of direct energy conversion (DEC) appeared in the literature in 1957. Experiments were conducted over the next ten years, which identified a number of problem areas. Research declined by the late 1960's due to technical challenges that limited performance. Under the Nuclear Energy Research Initiative the authors are determining if these technical challenges can be overcome with todays technology. The authors present the basic principles of DEC reactors, review previous research, discuss problem areas in detail, and identify technological developments of the last 30 years that can overcome these obstacles. As an example, the fission electric cell must be insulated to avoid electrons crossing the cell. This insulation could be provided by a magnetic field as attempted in the early experiments. However, from work on magnetically insulated ion diodes they know how to significantly improve the field geometry. Finally, a prognosis for future development of DEC reactors will be presented.
