Diamonds are supposedly abundantly present in different objects in the Universe including meteorites, carbon-rich stars as well as carbon-rich extrasolar planets. Moreover, the prediction that in deep layers of Uranus and Neptune, methane may undergo a process of phase separation into diamond and hydrogen, has been experimentally verified. In particular, high power lasers have been used to study this problem. It is therefore important from the point of view of astrophysics and planetary physics, to further study the production processes of diamond in the laboratory. In the present paper, we present numerical simulations of implosion of a solid carbon sample using an intense uranium beam that is to be delivered by the heavy ion synchrotron, SIS100, that is under construction at the Facility for Antiprotons and Ion Research (FAIR), at Darmstadt. These calculations show that using our proposed experimental scheme, one can generate the extreme pressure and temperature conditions, necessary to produce diamonds of mm3 dimensions.

Intense particle beams offer a new efficient driver to produce extended samples of high energy density (HED) matter with extreme physical conditions that are expected to exist in the planetary interiors. In this paper, we present two-dimensional hydrodynamic implosion simulations of a multi-layered cylindrical target that is driven by an intense uranium beam. The target is comprised of a sample material (which is water in the present case) that is enclosed in a cylindrical tungsten shell. This scheme is named LAPLAS that stands for Laboratory Planetary Science, and it leads to a low entropy compression. This means that the water sample is compressed to super-solid densities, ultra-high pressures, but relatively low temperatures. Such exotic conditions are predicted to exist in the cores of water-rich solar, as well as extrasolar planets. The beam parameters are chosen to match the characteristics of the particle beam that will be delivered by the heavy ion synchrotron, SIS100, at the Facility for Antiprotons and Ion Research (FAIR), at Darmstadt. It is to be noted that the LAPLAS scheme is an important part of the HED physics program at FAIR, which is named HEDP@FAIR. The simulations predict that the LAPLAS experiments will produce a wealth of information on the Equation-of-State properties of the exotic matter that forms the planetary cores. This information can be very helpful in understanding the formation, evolution and the final structure of the planets.

Russian institutes will participate in setting up the experiments HIHEX (Heavy Ion Heating and Expansion)and LAPLAS (Laboratory Planetary Sciences) as part of the FAIR program of scientific research. The appropriate numerical calculations of targets and preliminary experiments will be performed. Two vacuum chambers for studying the thermodynamic, transport, and optical properties of extreme states generated when matter is heated by intense heavy-ion beams will be developed and built. A system for obtaining a cylindrical beam and the corresponding cryogenic system for the LAPLAS experiments will be developed and built. Special attention will be focused on the development of proton radiography for diagnostics of extreme states of matter.The study of the thermodynamic, optical, and transport properties of matter at high energy density or extreme pressures and temperatures is of great interest for many areas of physics, such as astrophysics and planetary geophysics, physics of plasma with strong interparticle interaction, and elsewhere [1]. Powerful shock-wave facilities with explosives or lasers are the conventional means used for generating states of matter with high energy density.Intense heavy-ion beams open up new possibilities for experimental research at high energy densities [2]. A unique feature of energy deposition by heavy ions into matter gives rapid and uniform heating over macroscopic volumes of matter in a manner where the gradients of the temperature and density in the heated matter are much smaller than when other methods are used.The scientific association HEDgeHOB (High Energy Density generated by Heavy Ion Beams), whose membership consists of 175 scientists and engineers from 45 institutes and universities from 16 countries, was formed in the FAIR project to study the fundamental properties of matter at high energy density. Our country is represented by scientists from the Russian
