Profile consistency (or profile resilience) is the observation that profiles (of temperature, density, and pressure) often tend to adopt roughly the same shape (in tokamaks), regardless of the applied heating and fueling profiles. [1] [2] The resulting (stiff) profiles are known as canonical profiles. [3] This phenomenology is due to plasma self-organisation, [4] i.e., the feedback mechanism regulating the profiles (by turbulence) is often dominant over the various source terms.
