摘要：
We present experimental results on the interaction of short-pulse ultra-high-intensity laser beams with small size ("mass-limited'') targets. Several diagnostics (X-ray spectroscopy, K-alpha and optical imaging of target rear side) have been simultaneously used in order to characterize the laser-generated fast electron transport and energy deposition into the target material. Our results show that fast electrons are effectively confined inside the target by the induced space charge. This electrostatic confinement opens new opportunities to create "Warm Dense Matter'' states characterized by solid-state density and temperatures of the order of a few tens of eV.
