同轴等离子体枪的等离子体注入由于球形托卡马克的高径比小,不可能获得大的伏秒。目前,TST-M的伏秒是25 mVs,使用目前的电源。为了有效地利用有限的伏秒来加热等离子体,降低击穿的伏秒是很重要的,为此对同轴等离子体枪注入等离子体进行了试验。等离子体起始时间从0.8ms缩短到0.5ms,等离子体电流从8 kA增加到14 kA,证明了同轴等离子体枪的等离子体注入有助于伏秒消耗。
英文摘要
Plasma injection by coaxial plasma gunIt is impossible to have large volt second in spherical tokamak because of low aspect ratio. Presently, volt second of TST-M is 25 mVs using the present power supply. It is important to reduce the volt second for the breakdown, because plasma should be heated efficiently using the limited volt second.Plasma injection by coaxial plasma gun has been tested for this purpose. The time for the plasma initiation is reduced from 0.8 ms to 0.5 ms. Plasma current increases from 8 kA to 14 kA.It has been proved that the plasma injection by coaxial plasma gun helps volt second consumption.
