In magnetically confined plasmas, this state is thought to be responsible for the global transport phenomena of ''profile consistency'' and ''power degradation''. Profile consistency is the observation that profiles tend to have roughly the same shape, regardless of the power and location of the applied heating. | In magnetically confined plasmas, this state is thought to be responsible for the global transport phenomena of ''profile consistency'' and ''power degradation''.

Power degradation shows up in global transport scaling laws, and implies a sub-linear scaling of the plasma energy content with the injected power. | Power degradation shows up in global transport scaling laws, and implies a sub-linear scaling of the plasma energy content with the injected power. | ||
