Gyro-Bohm scaling is what one would expect for diffusive transport based on a diffusive scale length proportional to ρ<sub>i</sub> (the ion gyroradius). Bohm scaling, however, suggests that transport may [[Non-diffusive transport|not be diffusive]] and | Gyro-Bohm scaling is what one would expect for diffusive transport based on a diffusive scale length proportional to ρ<sub>i</sub> (the ion gyroradius). Bohm scaling, however, suggests that transport may [[Non-diffusive transport|not be diffusive]] and is not characterized by a typical scale length, i.e., is dominated by the scale length corresponding to the machine size (non-local). | ||
