Description

The ion acoustic decay instability has been investigated using UV collective Thomson scattering (CTS) in a large scale (∼1 mm) and hot (∼1 keV) plasma relevant to laser fusion. The instability was found to be easily excited. The spectrum of the electron plasma wave is consistent with simple theory. Collective Thomson scattering is shown to be a good tool for diagnosing the local electron temperature
