Artikelbeschreibung vom Verkäufer

16 pages, plus covers. Illustrations (some with color). Format is 10.5 inches by 8 inches. Number stamped on front cover. Stamp on rear cover. Some cover soiling. Corner has some curving. This is the executive summary of a detailed multi-volume program plan. This executive summary includes Goals, Objectives, and Applications; Fusion Advantages; Fusion Reactor Concept; Policy and Technical Variables; Program Logics; The Interplay Between Policy Variables, Technical Variables, and Program Logics. Also contains Options (a multiplicity of potential paths for each approach to fusion power); Roll-back planning; and Conclusions, as well as budget requirements, detail, and acknowledgments. This Program Plan spells out the options available to the Division of Magnetic Fusion Energy under a range of possible funding assumptions called "Program Logics." As such, it represents a Division document and not necessarily the views of the top ERDA management. The Division believes, however, that the range of program logics and options presented will cover any eventualities which may arise in the course of setting program strategies with ERDA management, OMB, and Congress. Magnetic confinement fusion is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of fusion energy research, along with inertial confinement fusion. The magnetic approach began in the 1940s and absorbed the majority of subsequent development. Fusion reactions combine light atomic nuclei such as hydrogen to form heavier ones such as helium, producing energy. In order to overcome the electrostatic repulsion between the nuclei, they must have a temperature of tens of millions of degrees, creating a plasma. In addition, the plasma must be contained at a sufficient density for a sufficient time, as specified by the Lawson criterion (triple product). Magnetic confinement fusion attempts to use the electrical conductivity of the plasma to contain it through interaction with magnetic fields. The magnetic pressure offsets the plasma pressure. Developing a suitable arrangement of fields that contain the fuel without excessive turbulence or leaking is the primary challenge of this technology. The development of magnetic fusion energy (MFE) came in three distinct phases. In the 1950s it was believed MFE would be relatively easy to achieve, setting off a race to build a suitable machine. By the late 1950s, it was clear that plasma turbulence and instabilities were problematic, and during the 1960s, "the doldrums", effort turned to a better understanding of plasma physics. In 1968, a Soviet team invented the tokamak magnetic confinement device, which demonstrated performance ten times better than alternatives and became the preferred approach.
