Abstract
The possibility of using a Langmuir probe as a detector of sound waves in a weakly ionized gas is demonstrated by means of a simple experiment ill which an acoustic pulse transmitted through the plasma column of all argon discharge is detected by such a probe. Using this technique, the speed of sound and from it the neutral-gas temperature have been determined in all argon discharge as a function of gas flow, pressure, and discharge current.
