Abstract

The size distribution of dust particles present in FTU after disruptions has been evaluated in the range 0.05 μm-0.1 μm using the Thomson scattering system. Rayleigh approximation has been used to estimate the dust size. The distribution, although the radii considered do not differ more than an order of magnitude, behave like a power law. The laser energy density far exceed that necessary to vaporize, at least partially, the particles. This can affect the previous estimate of the particle sizes, and suggests that the effective radii might be larger than the estimated values. A preliminary analysis on the broad band signal is presented. © 2008 American Institute of Physics.
