Pulsed High Beta Plasmas

Pulsed High Beta Plasmas contains the proceedings of the Third Topical Conference on High Beta Plasmas held in Oxfordshire, UK, on September 9-12, 1975. The papers explore various aspects of pulsed high beta plasmas and cover topics such as reversed field pinches; mass flow stabilization of plasma confined by helical magnetic fields; cross-field instabilities in theta-pinch plasmas; and soft X-ray emitting plasma structures during the main neutron emission of plasma foci. Experimental observations of the self-reversal of a toroidal magnetic field in pinches are also presented.
This book is comprised of 98 chapters and begins with a discussion on experimental results concerning a high beta stellarator, followed by a review of toroidal theta-pinch theory. The reader is then introduced to relaxation of toroidal discharges; equilibrium and stability of a diffuse high-beta Tokamak; spectroscopic studies of high beta plasma; and pulsed radiation from focused plasmas. Subsequent chapters explore the compression and kink instabilities of reversed field pinches; self-inductance changes in a plasma focus; interactions of high-energy plasma clusters with a longitudinal magnetic field; and electromagnetic implosion of large-diameter liners. The linear theta pinch as a 14-neutron source is also described.
This monograph will be a valuable source of information for physicists.
