Fast ions produced by laser irradiance of the front side of a wire target also appeared on the back side. The speed of the energy transport around the wire was measured at approximately 2*10<sup>8</sup> cm s<sup>-1</sup> and its temperature gradient was approximately 5*10<sup>5</sup> eV cm<sup>-1</sup>. The energy was transported a lateral distance of 1500 mu m away from the laser focal spot (100 mu m diam.) when protons were one of the plasma constituents. However, for a pure carbon target, the energy spread was not observed down to a distance of 300 mu m.
