The plasma interactions with propellants experiment (PIPE) facility is designed for the study of materials and propellants exposed to a pulsed, high-heat flux plasma produced with an electrothermal plasma gun. PIPE is powered by a single 340-μF capacitor with a maximum charging voltage of 10 kV, for a maximum discharge energy of 17 kJ. This paper describes discharge voltage and current measurements made with a high-frequency compensated voltage divider and a Pearson coil. For these experiments, the gun was operated in air at 2 torr at discharge energies between 1.1-8.1 kJ. The maximum current ranged between 10-45 kA. The maximum gun power ranged between 30-160 MW. Typical discharge durations were on the order of 100 μs.
