Volt-second saving by lower hybrid current drive in JT-60

The volt-second consumption of the Ohmic primary circuit is reduced by lower hybrid current drive during the current rise phase. Most of the lower hybrid power is consumed in compensating the resistive voltage of typically 0.8 V. Up to 2.5 V · s of flux is saved by 2 MW × 2.5 s of lower hybrid power, which could be projected to several tens of volt-seconds in ITER class reactors. In most cases, for lower hybrid assisted current ramp-up discharges the safety factor q can pass the value qa = 3 without causing any disastrous MHD instabilities leading to a major disruption.

オーミック一次回路のボルト秒消費は、電流立ち上げ段階における低ハイブリッド電流駆動によって低減される。低ハイブリッド電力の大部分は、典型的には0.8 Vの抵抗電圧を補償するために消費される。2 MW × 2.5 sの低ハイブリッド電力により、最大2.5 V·sの磁束が節約され、これはITER級の炉では数十ボルト秒に相当すると予測され得る。ほとんどの場合、低ハイブリッド支援電流立ち上げ放電において、安全係数qは大規模ディスラプションを引き起こすような破壊的なMHD不安定性を生じることなく、q = 3の値を通過することができる。
