Study of the fundamental properties of matter at high energy density created by an intense ion beam

Abstract

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
