摘要:

双电子温度等离子体是由两种具有不同温度和密度的等离子体扩散而产生的。该方法简单,并提供了一个足够的控制等离子体参数。研究表明,通过改变两个等离子体的放电电流,可以有效地控制两个电子团的温度和密度。在等离子体中激发离子声(IA)波,并使用平面朗缪尔探针进行检测。测量波的阻尼振幅,并将其用作诊断工具,用于建立双电子组件的存在。该方法可用于等离子体加工工业中热电子密度和温度的控制。

英文摘要:

A two-electron temperature plasma is produced by the method of diffusion of two different plasmas with distinct temperatures and densities. The method is simple and provides an adequate control over the plasma parameters. The study reveals that the temperature and density of both the electron groups can be effectively controlled by just changing the discharge currents of both the plasmas. An ion-acoustic (IA) wave is excited in the plasma and is detected using a planar Langmuir probe. The damped amplitude of the wave is measured and is used as a diagnostic tool for establishing the presence of two-electron components. This production method can be helpful in controlling the hot electron density and temperature in plasma processing industries.
