A system is said to be in this state when it | A system is said to be in this state when it is at an attractive critical point at which it behaves as in a phase transition (i.e., the spatial and temporal scales are scale-invariant, or nearly so). | ||
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''.
