Book Description
Runaway electrons produced during normal discharges in the Oak Ridge Tokamak (ORMAK) have been studied with a hard x-ray diagnostic system along with most of the other diagnostics available on this machine. It is found that runaways can attain maximum energies of up to 10 MeV and be contained over times of typically 50 msec. A simple physical model is proposed that is consistent with most of the observed high energy runaway phenomena. Some properties of the overall runaway distribtion generated in tokamaks are inferred from these results and are discussed in terms of runaway generation, acceleration, and transport.

Book Description
High energy runaway electrons in the Oak Ridge tokamak ORMAK have been investigated through measurement of the bremsstrahlung produced when these electrons leave the discharge and strike the limiting aperture of the torus. The experimental results have been interpreted in terms of a classical single-particle model appropriate for collisionless particles in a tokamak, and it has been found that most of the confinement properties of high energy runaways in ORMAK can be understood on this basis. An experiment designed to directly test this model has disclosed an anomalous transport which has been described by a runaway diffusion coefficient D approximately 102 to 104 cm2/sec appropriate for runaways near the outside of the plasma. A discussion of the possible mechanisms for this anomalous transport is given.

Book Description
Diagnostics for Fusion Experiments provides information pertinent to the fundamental aspects of plasma physics. This book presents the requirement in measuring electron and ion temperatures at the multi-key level. Organized into four parts encompassing 36 chapters, this book begins with an overview of the principles and methods by which analysis of the fast neutrals obtained by charge exchange in the plasma volume can be utilized to obtain the plasma ion temperature. This text then examines the use of active particle beam systems in plasma diagnostics. Other chapters consider the source function for production of fast neutrals in Tokamak plasma. This book discusses as well the special diagnostic needs of mirror machines, with focus on diagnostics involving the higher-power neutral beams used with them. The final chapter deals with the standard mirror fission-fusion hybrid, tandem mirror, and the field-reversed mirror. This book is a valuable resource for experimental physicists and research workers.
