Description
A large amplitude m=1 mode is excited by LHCD in the WT-3 tokamak (a=20cm, R=65cm, Bt≤1.75T). The mode excitation is accompanied with decrease of the magnetic shear near the q=1 surface and peaking of the soft X-ray (SX) emissivity profile, suggesting that the mode is a pressure driven mode. The mode is suppressed by ECH near the q=1 surface, while enhanced by ECH near the plasma center. The mode stabilization is accompanied with a local enhancement of the SX emissivity near the q=1 surface. (author)
