Abstract
Electrode ablation in a rail type of electromagnetic shock tube has been studied. Cathode ablation was found to be present over a wide range of experimental parameters whereas anode ablation was found to be immeasurably small. The parameters varied included the drive current, gas pressure, and the electrode material. Observations of current sheet velocity were interpreted as evaporation of cathode material from cathode spots. The ablation series determined from velocity data for the metals tested was: mild steel, Zn, Cu, Mo, in order of decreasing amount of ablation.
