Abstract

A quasi-steady-state lower-hybrid current-drive operation is demonstrated in the Alcator C tokamak at densities up to ne1×1014 cm-3. The current-drive efficiency is measured experimentally over a wide range of densities and magnetic fields. The radial distribution of high-energy x rays indicates that the current-carrying electrons peak near the plasma axis.
