摘要: This volume is dedicated to unconventional approaches fusionthose thermonuclear reactors that, in comparison with Tokamak and other main lines, have received little attention the worldwide scientific community. Many of considered are still embryonic stages. The authors-an international group active nuclear scientists engineers-focus on parameters achieved use these meaning most recent physical studies their implications for future. They also compare conventional ones, particular, stressing non-plasma-physics requirements fusion reactors. Unconventional compact toroids, linear systems, multipoles considered, as ''almost conventional'' machines: stellarators, mirrors, reversed-field pinches, EBT.
