Steady-state LHCD operation has been extended to pulse lengths beyond one hour in TRIAM-1M. Hall-effect sensors were used in the feedback loop for plasma position control. In the long duration discharge, a plasma current of 22 - 25 kA and a line-average electron density of about 2 × 1012 cm-3 were maintained nearly constant and no significant impurity accumulation was observed. High density (n̄e ≅ 1.0 × 1013 cm-3) current drive discharges were obtained by improving the accessibility of the plasma to LH waves. The current drive efficiency was improved by increasing the plasma density. The bulk plasma has better confinement properties than a low density OH plasma.
