Triple Langmuir probe diagnosis of transient plasma created by hypervelocity impact

摘要: To acquire the characteristic parameters of plasma generated by hypervelocity impact, experimental system and a new Triple Langmuir probe diagnostic are established in paper. technology does not require voltage or frequency sweep compared to other methods. The allows direct display electron temperature semidirect density appropriate system, this method eliminates time consuming data analysis required curve-fitting current-voltage characteristics. As an example application timedependent plasmas measurement, were measured impact experiments. Experimental results show that can be well used measure time-evolution plasma.
