Flush-mounted probe diagnostics forargon glow discharge plasma
A comparison is made between plasma parameters measured by a flush-mounted probe (FP) and a cylindrical probe (CP) in argon glow discharge plasma.Parameters compared include the space potential, the plasma density and the effective electron temperature.It is found thatthe ion density determined by the FP agrees well with the electron density determined by the CP in the quasi-neutral plasma to better than 1 0%.Moreover, the space potential and effective electron temperature calculated from electron energy distribution function (EEDF) measured by the FP is consistent with that measured by the CP over the operated discharge current and pressure ranges.These results presentthe FP can be used as a reliable diagnostic tool in the stable laboratory plasma andalso be anticipated to beapplied in other complicated plasmas, such as tokamaks, the region of boundary-layer and so on.
