摘要
The hydrodynamic response of thin planar targets to the ablative pressure pulse induced by a high-power proton beam has been investigated experimentally at the Karlsruhe Light Ion Facility using time-resolved laser-Doppler velocimetry. An analytical acoustic model was established which allows a semiquantitative interpretation of the phenomena observed. Details in the measured ablation pressure history could be explained by the particularities of the proton beam. The evolution in time of the depth of the energy deposition zone deduced from our experiments is in good agreement with the proton energy and stopping range increase during the voltage rise of the generator pulse.
