Abstract

High confinement improvement (H-factor) relative to the IPB98(y,2) scaling law [1], stability and & betalN are achieved in JET hybrid scenario pulses due to formation of specific safety factor (q) profiles with broad flat region around q∼1 in the plasma core and steep dq/dr at the edge. The replacement of the C-wall with Be/W-wall caused changes in the impurity content with effect on the q-profile, MHD, radiation and tE. An interaction between these factors in hybrid pulses with ILW has been analysed using transport modelling and important statistical tendencies identified.
