PELLET FUELLING OF JET PLASMA DURING OHMIC, ICRF AND NBI HEATING
Pellet fuelling experiments have been performed on JET using a single - shot pneumatic injector giving 4.6mm (4.5x10**21 D atoms) and 3.6mm (2.2x10**21 D atoms) diameter cylindrical deuterium pellets with velocity 0.8<or=V(km.s**-)<or=1.2. Z-eff<1.5 with n-D/n-e-1 on axis has been achieved. In configurations with a magnetic seperatrix, peaked electron density profiles with n-e(o)/n-e-2 are obtained, with n-e(O)approximately equal 1.2x10**20m**-3 and T-e(O)approximately equal 1keV. Separately, high value of n-D(O)T-ET-i(O)=1.3x10**20m**-3.s.keV at T-i(O)=6.5keV has been obtained with pellet fuelling following by NBI heating.
