Temperature measurements in an argon plasma jet.

The aim of this study was to establish reliable temperature distributions, within an argon plasma jet in both the cases of an unconstrained jet discharging to the atmosphere and a jet impinging on a cooled metal surface under various input conditions. An optical technique, the Two Line Relative Intensity Method was employed with both Ionic/Atomic and Atomic/Atomic Line Combinations. Results are presented in Chapter 5 and are compared with published data in Chapter 6 and have been published.* Noise measurements have been made and represent an initial investigation into turbulent fluctuations within the jet. A novel technique of collimation and scanning of the plasma get is described in Appendix 3. *"Temperature and Noise Profiles in an Argon Plasma Jet". R.W. Maxwell and M.J. Ruddy, I.E.E.
