Impurity (Li and C) pellet experiments, which began at TFTR in 1989, and are expected to continue at least through 1991, have continued to produce new and significant results. The most significant of these are: (1) improvements in TFTR supershots after wall-conditioning by Li pellet injection; (2) accurate measurements of the pitch angle profiles of the internal magnetic field using the polarization angles of line emission from Li{sup +} in the pellet ablation cloud; and (3) initial measurements of pitch angle profiles using the tilt of the LI{sup +} emission region of the ablation cloud which is stretched out along the field lines.
