Time-Resolved Emission Spectroscopy Measurements during the Restrike Period in Arc Plasma Torch
Water-argon plasma torch and jet: (a) schematic view of the torch, (b) photograph of the torch, (c) image of the plasma jet (camera (Canon EOS 450D), exposure time in the order of milliseconds), and (d) image of the plasma jet (high-speed camera (Photron), exposure time in the order of microseconds). Images were taken at the arc current 500 A and argon flow rate 12 slm.
