| Description/Abstract | Application of IBW power to neutral beam heated PBX-M discharges was observed to progressively peak the electron density profile, inducing gradients in excess of 5[times]10[sup 12] cm[sup [minus]4] and central density up to 8[times]10[sup 13] cm[sup [minus]3]. Abated MHD activity occurred during the peaking phase. Core ion thermal diffusivity dropped during the same period to values neighboring 1 m[sup 2]/s. Induced large n[sub e] gradients were spatially correlated with the IBW deposition profile. Bootstrap current induced in mid minor radius region broadened the total current profile.
