Overview
- Treats both experimental and theoretical aspects of quasicoherent potential oscillations
- Presents a comparison of the unique experimental data on the core electric potential from the TM-4 and T-10 tokamaks as well as from the TJ-II stellarator
- Provides a link between potential and confinement over the whole operational limits of the devices under experimental study, including regimes with various means of heating and regimes with improved confinement

About this book
This work introduces heavy ion beam probe diagnostics and presents an overview of its applications. The heavy ion beam probe is a unique tool for the measurement of potential in the plasma core in order to understand the role of the electric field in plasma confinement, including the mechanism of transition from low to high confinement regimes (L–H transition). This allows measurement of the steady-state profile of the plasma potential, and its use has been extended to include the measurement of quasi-monochromatic and broadband oscillating components, the turbulent-particle flux and oscillations of the electron density and poloidal magnetic field.
Special emphasis is placed on the study of Geodesic Acoustic Modes and Alfvén Eigenmodes excited by energetic particles with experimental data sets. These experimental studies help to understand the link between broadband turbulent physics and quasi-coherent oscillations in devices with a rather different magnetic configuration.
Thebook also compares spontaneous and biased transitions from low to high confinement regimes on both classes of closed magnetic traps (tokamak and stellarator) and highlights the common features in the behavior of electric potential and turbulence of magnetized plasmas.
A valuable resource for physicists, postgraduates and students specializing in plasma physics and controlled fusion.
