Compression of a cylindrical hydrogen sample driven by an intense co-axial heavy ion beam

The compression of a cryogenic hydrogen cylindrical sample contained in a hollow gold target driven by an intense co-axial uranium beam has been studied. The ion distribution is assumed to be Gaussian in space and parabolic in time. Thehydrodynamicsofthetargetisanalyzedbymeansofone-andtwo-dimensionalnumericalsimulations.Aparametric study is performed to achieve the maximum average hydrogen density and temperature as a function of the sample radius, total number of ions and spread of the spatial ion distribution.Awindow in the beam-target parameters for which hydrogen compression is higher than a factor of 10 and temperature is below 0.2 eV has been found by considering a single bunch that contains 2 10 11 uranium ions delivered in 100 ns. In this range of high densities and low
