| 摘 要： | 提出了新型筒状双层闪络板等离子体枪及其驱动电路的设计方案。枪内层接脉冲高压,均布160个电弧点,每个电弧点由中心焊盘及填充TiH2粉末的外围凹槽组成,TiH2粉末用硅酸钠粘接于凹槽中;通过100Ω电阻连接每个高压焊盘与接地端,电极间隙中产生等离子体。通过放电实验得出:当由3 kV,20μF电容器驱动时,脉宽为1.5μs、幅值约150 A的电流通过枪,产生的等离子体密度为1013~1014cm-3,存在时间0.5μs,等离子体定向速率达到5 cm/μs。实验证明:该闪络板等离子体枪可靠性强,可重复产生均匀等离子体。

| Abstract: | A novel double-layer cylinder flashboard plasma gun system is put forward.The inner flashboard of the plasma gun is connected to high voltage,with 160 arcing points uniformly distributed on it.Each arcing point consists of a central electrode and a groove filled by TiH2 powder.The powder is bound to the groove with a sodium-silicate binder.TiH2 is chosen for negative hydrogen production,and one can fill the grooves with other materials for other purposes if needed.Each high voltage electrode is connected wi... |
