超声分子束注入是磁约束聚变装置常用的补充加料手段之一,并对等离子体流和湍流产生重要影响。实验在J-TEXT装置上开展,采用三台阶朗缪尔探针阵列,在欧姆放电氢等离子体中观测了超声分子束注入对边缘流和湍流的影响。结果表明:超声分子束注入后测地声模带状流、湍流及其驱动的粒子输运分别减小40%~60%、50%~70%及60%~70%,且伴随着离子-离子碰撞频率增大;湍流雷诺协强及湍流对测地声模带状流做功明显减小;密度及温度梯度降低。进一步分析表明,测地声模带状流减弱主要归因于湍流雷诺功的降低和碰撞率的增加 ...

Radiation characteristic measurement of low temperature plasma under atmospheric pressure [PDF]
本文在自行设计的放电电极板上实现常压下的空气辉光放电(APGD),产生出一薄层的低温等离子体,利用光栅单色仪及测试声强和温度的仪器对所产生的等离子体的光辐射、声辐射和热辐射特性进行实验测量。数据处理后的分析结果表明,该APGD等离子体的光辐射强度及声辐射和热辐射强度,以及总辐射能量基本上都与电极板的加载功率呈线性关系,而且各种形式的能量各占比例是一定的。研究结果表明可以通过沿面APGD的辐射特性与加载功率之间的关系来描述APGD等离子体的特性,以及控制等离子体的产生量。A thin layer of ...
