摘要

1. Introduction In fusion tokamaks saving the flux swing during the current start-up and ramp-up phase is effective to prolong the burning duration, during which a very low loop-voltage is sufficient to maintain the toroidal current. Among various methods for saving, effective use of electron cyclotron heating and current drive (ECH/ECCD) power is important since the ECH/ECCD system would be already fabricated in fusion tokamaks to keep the burning phase stable via profile control. While Ordinary (O) waves at fundamental resonance frequency are supposed to be employed for control of the burning plasmas, extraordinary (X) waves are more useful than the O waves in low temperature and low density start-up plasmas [1]. Here X-waves are shown to be also useful in current ramp-up plasmas for an ITER case. It is also shown that a flux swing of about 10 volt seconds can be saved by 10 MW X-wave ECCD at initial current ramp up stage up to 1MA using a simple model for plasma current loop.
