• Study on temperature measurement of two-electrode TIG arc plasma

抄録

Measurements of arc plasma are important for determining the associated physical properties. Such measurements usually involve the use of spectroscopic techniques to measure temperature distribution in free-burning arcs. Most of the studies have reported the temperature of axially symmetric arc plasma using Abel inversion. This method cannot be used for axially asymmetric arc plasma such as two-electrode TIG arc plasma. It is complex phenomenon because the arc plasma generated from each electrode is affected by the other due to electromagnetic force. We measured the temperature distribution of tandem TIG arc plasma three dimensionally with one camera rotation system. The measurement method includes the multi-directional detections and the image reconstruction technique: Maximum Likelihood-Expectation Maximization (ML-EM). We evaluated the influence of number of detection directions on the reconstruction by virtual intensity distribution and found that the sufficient direction number is 6. As a result, we could measure the temperature distribution of the inclined, drawn and coupled arc plasma provided by two-electrode TIG arc.
