The objective of this work is to obtain an increased understanding of plasma jet processes as related to the use of the plasma jet arc to test ablating systems. Plasma jets were constructed and operated as sources for optical and time-of-flight mass spectrometry. Optical spectroscopic methods were used to identify chemical species and state of excitation when inert gas or air was used as the plasma arc working medium. Time-of flight mass spectrometry was not developed to the point where species could be identified.
