Abstract

In the Large Helical Device (LHD), some reactor-oriented experiments, i.e. high beta, high ion temperature, steady state operation, have produced remarkable progress in recent experimental campaigns. By optimizing the rotational transform, an average beta value of 4.3 %, which is the highest on record for helical devices, was achieved. The ICRF sustained steady-state discharges for more than 30 minutes, these were also successfully performed with the aid of the magnetic axis swing technique for the reduction of the heat load to the plasma-facing component. In the discharge, the total input energy to the plasma reached 1.3 GJ, which also established a new record.
