We used the tone burst floating probe method to measure plasma parameters in a hollow cathode discharge. In this method, the electron temperature is directly calculated from a shift in the floating potential of the burst interval when a tone burst signal is applied to a probe through an intermediary blocking capacitor. The tone burst signal is a signal that applies an ac signal for a fixed time and turns off the remaining time of the cycle. It was possible to measure the same electron temperature as in the floating probe method that we previously reported. In the tone burst floating probe method, it is possible to measure the ion current by a shift in the floating potential from the time constant of the burst interval. This is a new measurement method that can measure the plasma density from the ion current and the electron temperature during the tone burst signal input.

使用音爆波对电子温度和电子密度进行新型等离子体诊断测量

我们使用音调突发浮动探针方法来测量空心阴极放电中的等离子体参数。在该方法中，当音调猝发信号通过中间阻塞电容器施加到探针时，电子温度直接根据猝发间隔的浮动电位的变化来计算。音调猝发信号是在固定时间内施加交流信号并关闭循环的剩余时间的信号。可以测量与我们之前报道的浮动探针方法相同的电子温度。在音调突发浮动探针方法中，可以通过浮动电位相对于突发间隔时间常数的偏移来测量离子电流。
