Abstract

Numerical analysis of the compression of a cylindrical cryogenic hydrogen sample surrounded by a high-density metallic shell driven by a heavy ion beam has been performed. The beam power profile is assumed to be parabolic in time and Gaussian in space and is made of uranium ions with a kinetic energy of 2.7 GeV/u. The beam center is positioned off axis and rotates around the target axis to provide a uniform annular energy deposition area. An acceptable symmetry in pressure is achieved if the number of revolutions is equal to or larger than 10. The maximum density and pressure of the hydrogen sample is studied as a function of the spread of the beam power Gaussian distribution and the rotation radius. This configuration leads to compressions of the order of 10 and a temperature of a few thousand Kelvin in hydrogen.
