A demonstration of the 'Isotope Wind Tunnel Principle' in JET and its use in Predicting Reactor Performance
ELMy H-mode pulses have been obtained with different hydrogenic isotopes but having the same profiles of the dimensionless parameters p, b, v and q, to test whether the confinement scale invariance principle is valid in a tokamak. The fact that the confinement times, the ELM and sawtooth frequencies in the two pulses all scale as expected suggests that the invariance principle is satisfied through the plasma radial extent, in spite of differing physical processes taking place in the plasma centre, core and edge regions. An application of this isotope windtunnel technique to predicting D-T performance of next step devices is discussed.
