Ion Acoustic Waves in a Density Gradient
Abstract
A damping-growth transition for ion acoustic waves propagating in a non-uniform plasma (e-folding lengths for the density ln) is observed at wavelengths λc ≈ 2 π ln. The experiment, conducted in a Q-device, supports calculations performed in connection with the problem of solar corona heating
