Abstract

A lower hybrid current drive (LHCD) was applied to stabilize the neoclassical tearing modes in high β plasmas on COMPASS-D. The high β plasmas were established using high power electron cyclotron resonance heating. Stabilization increased the plasma performance by approximately 15%-20%, and was achieved with an LHCD power of just 10% of the total ECRH heating power.
