Studies were made on the tail flame of a highintensity electric arc to determine its suitability as a medium for testing materials under sustained hightemperature gaseous flow. An electrode geometry for stable operation was established. Measurements are reported on the temperature and velocity distribution in the tail flame at various pressures. Observations on the electrodynamic, magnetic, and thermodynamic properties of the tail flame were made. Surface heat flux rates were measured at 1.0 and 0.1 atmospheres on copper bodies in thermal equalibrium Diffusivity measurements were made in the taail flame on OFHC copper and graphite plates.
