Stellarator and Heliotron DevicesThis monograph describes plasma physics for magnetic confinement of high temperature plasmas in nonaxisymmetric toroidal magnetic fields or stellarators. The techniques are aimed at controlling nuclear fusion for continuous energy production. While the focus is on the nonaxisymmetric toroidal field, or heliotron, developed at Kyoto University, the physics applies equally to other stellarators and axisymmetric tokamaks. The author covers all aspects of magnetic confinement, formation of magnetic surfaces, magnetohydrodynamic equilibrium and stability, single charged particle confinement, neoclassical transport and plasma heating. He also reviews recent experiments and the prospects for the next generation of devices. |

Page 1 - The three states of matter, solid, liquid, and gas, are well known to us. As the temperature is elevated, solid is liquefied and liquid is evaporated to form a gaseous state. If we further increase the temperature, the molecules constituting the gas are decomposed into atoms and the atoms are then decomposed into electrons and positively charged ions. The degree of ionization increases as the temperature rises. For the case of hydrogen gas at normal pressure, the ionization becomes almost complete...

Page 60 - As in any numerical calculation, the procedure involves compromises. A short time step improves the accuracy but increases the number of operations. On the other hand, a large time step leads to inaccuracies that may mask important physical processes. The goal is to extract the maximum amount of information through the minimum time of computation.
Page 2 - Progress in plasma physics emerged in the second half of this century, motivated by two very important applications: space exploration and thermonuclear fusion. In the 1940s, radio-astronomers discovered that more than 99% of the universe is in a plasma state. Since the first Sputnik spacecraft was launched in 1954 into an orbity circling the Earth, a number of space probes have been used to collect data on the Earth's magnetosphere.

Page 56 - Coulomb potential of any charged particle (to be referred to as the test particle) induces an electric polarization because it attracts (or repels) the charge of the opposite (or same) sign. The polarization charge tends to cancel the charge of the test particle and restricts the effect of its Coulomb potential to a finite range.
