Simulations of 78 JET ITER-like wall D-D discharges and 2 D-T reference
discharges are carried out using the TRANSP predictive integrated
modeling code. The time evolved temperature and rotation profiles are
computed utilizing the Multi-Mode anomalous transport model [T. Rafiq,
et al., Phys. Plasmas 20, 032506 (2013)]. The discharges involve a broad
range of conditions including scans over gyroradius, collisionality, and
values of q95. The D-T reference discharges are selected in anticipation
of the D-T experimental campaign planned at JET in 2019. The simulated
temperature and rotation profiles are compared with the corresponding
experimental profiles in the radial range from the magnetic axis to the
ρ = 0.9 flux surface. The comparison is quantified by calculating the
RMS deviations and Offsets. Overall, good agreement is found between
the profiles produced in the simulations and the experimental data. It
is planned that the simulations obtained using the Multi-Mode model will
be compared with the simulations using the TGLF model [G.M. Staebler,
et al., Phys. Plasmas 14, 055909 (2007)].
