摘要
The technique of probe measurements (experiment and theory) is applied in a dense, strongly ionized inert-gas plasma at atmospheric pressure. The measurements are performed in a high-current (250-550 A) free-burning argon are with a thermionic cathode. As a control technique we used spectroscopic measurements. Comparison of calculation with experiment reveals goad agreement. The possibility of determining the plasma potential from the measured floating-probe potential is demonstrated.
