Abstract

AN IMPROVED TRITON BURN-UP CODE, USING THE SHOT TO SHOT MEASURED PLASMA PARAMETERS AND PROFILES, IS USED TO PREDICT THE 14 MEV TO 2.5 MEV NEUTRON FLUENCE RATIO UNDER THE ASSUMPTION OF CLASSICAL SLOWING DOWN. THIS NEUTRON FLUENCE RATIO IS COMPARED WITH THE EXPERIMENTAL FLUENCE RATIO FROM THE FT TOKAMAK FOR VARIOUS TOROIDAL MAGNETIC FIELDS AND PLASMA CURRENTS. ASSUMING A CURRENT DISTRIBUTION J(R)-TE(3/2), IT IS FOUND THAT FOR Q(A)>3, THE CONFINEMENT IS CLASSICAL, WITHIN THE ERROR BARS, BUT FOR Q(A)<3, THE CONFINEMENT SEEMS PROGRESSIVELY TO DETERIORATE WITH INCREASING MHD ACTIVITY. ASSUMING ON THE CONTRARY THE KADOMTSEV SAWTOOTH MODEL FOR THE CURRENT DISTRIBUTION, SUCH DETERIORATION DOES NOT SEEM TO OCCUR.
