Proposed high energy density physics research using intense particle beams at fair and CERN: The HEDgeHOB collaboration

Abstract

We present results of our theoretical investigations that have been carried out over the past years to assess the potential of intense heavy ion beams that will be generated at the future FAIR facility, at Darmstadt, to study the physics of high energy density (HED) states in matter. It has been found that three different experimental schemes, namely, HIHEX, LAPLAS and Ramp Compression can be employed for this purpose.In the first scheme, HED state are induced in a sample material employing isochoric and uniform heating by an intense ion beam that is followed by isentropic expansion of the heated material. One can study the equation of state (EOS) properties of these exotic states of matter using this scheme. The second scheme involves a low- entropy compression of a test material like hydrogen or water in a multi-layered cylindrical target that is imploded by a hollow beam with an annular focal spot. This scheme generate physical conditions that are expected to exist in the interiors of the giant planets. The third scheme is suitable for a shockless compression of a sample to study material properties under dynamic conditions.
