Langmuir Probe Diagnosis of High Temperature and High Density Plasma Generated by shock tube

The principle of plasma diagnosis by Langmuir probe was described, and the parameters of high temperature plasma produced by shock tube was diagnosed. The plasma density and electron temperature were acquired by calculated according to the volt-ampere characteristic curve. The Langmuir probe results were also compared with ion collector results and they are in agreement of same variation with the mach number ranging from 9Ms～24Ms. The reliability and correctness of using this test system to measure parameters of plasma is conformed. And it also offers an effective way to plasma diagnosis of high temperature and high density.
