An experimental study of Ion Acoustic (IA) wave propagation is performed to investigate the effect of neutral density for argon plasma in an unmagnetized linear plasma device. The neutral density is varied by changing the neutral pressure, which in turn allows the change in ion-neutral, and electron-neutral collision mean free path. The collisions of plasma species with neutrals are found to modify the IA wave characteristics such as the wave amplitude, velocity, and propagation length. Unlike…

Journal of Geophysical Research
The journal Terrestrial Magnetism and Almespheric Electricity will appear under the new title Journal of Geophysical Research, indicating a widening of the scope of the journal, though the scope has long transcended the limits implied by the title now discontinued.
