DIII-D #166613

Description

This H-mode discharge was part of an experiment designed to test the impact of neon injection on the pedestal pressure at varying NBI heating powers. The analysis shown here was conducted prior to the neon injection which begins at 2.0 secs. This case has a NBI power of 6.3MW. The major plasma parameters are Bt=2.0T, Ip=1.3MA, kappa=1.8, and delta(u,l)=(0.32,0.57).
