Anomalous transport in tokamaks induced by electrostatic instabilities
The nonlinear extensions of the gyro and drift kinetic equations, which describe ion and electron behaviour in low frequency, finite mode number drift oscillations, are given and discussed. The corresponding anomalous transport equations are stated and interpreted. A specific nonlinear saturation mechanism of drift waves and the corresponding calculated spectra are described. The results of a transport code based on these first principle considerations are compared with experiment. Finally, other approaches to the problem of anomalous transport are briefly sketched.
