A b s t r a c t . Electromagnetic turbulence thought to be responsible for anomalous transport in magnetic confinement devices such as tokamaks is very complicated, involving a multitude of physical processes, length and time-scales. It cannot be investigated by traditional linear theories any more than aerodynamic fluid turbulence. The relatively longer wavelength (kxPi * , relatively long wavelength {k^pi -C l ; m , n up to 20-30) drift-like fluctuations using a periodic cylinder (r,9, = -g) geometry and tokamak ordering (ie -|
