A CO 2 laser scattering experiment performed on a dense plasma focus is reported. The optical set-up permitted (by variation of the incident wave polarization) determination of the scattering process, either collective scattering or overdense scattering from a critical surface. Overdense scattering was observed in the post pinch plasma and was found to be correlated spatially with bright X-ray emitting regions as determined by soft X-ray pinhole photographs. Collective scattering from the pinch or post pinch was not observed suggesting that bulk turbulence is not a significant mechanism for ion heating. Temporal correlation of the scattered signal with hard and soft X-rays, neutrons and dI/dT is also presented.
