The soft x-ray radiation intensity ([5, 45]) emitted by a carbon plasma after the interaction of a short ultrahigh-intensity KrF laser pulse with preplasmas of different scale lengths was investigated. This was done spectrally and temporally resolved by means of a time-resolving spectrograph. A strong increase in the duration of this radiation with larger scale lengths is observed, which is qualitatively explained by a shift of the heat deposition to smaller densities.
