Toroidal Alfven eigenmodes and other Alfvenic modes have been predicted to be destabilized by the presence of a fusion [alpha] population in TFTR and future D-T machines, possibly resulting in significant loss of the fast [alpha] population. A new array of Mirnov coils has been added primarily for the measurement of moderate to high toroidal mode numbers. Initial measurements of the [ital n] number of ICRF generated toroidal Alfven eigenmodes modes is presented. The array has also been used to measure the toroidal correlation length of the edge magnetic turbulence.
