The unique properties of heavy-ion beam-driven high-energy density matter (HEDM), characterized by macroscale uniformity, extended volumetric dimension, and material diversity, present novel opportunities for advancing high-energy density physics (HEDP). The High-Intensity Heavy-Ion Accelerator Facility (HIAF), a cornerstone project which is initiated during China’s 12th Five-Year Plan, is currently being accelerated in construction. After completion, it will become a primary platform for experimental research on the HEDP phenomenon induced by intense heavy-ion beams. In this work, a self-developed 1D radiation hydrodynamics code, Aardvark, is used to simulate the interaction dynamics between uranium ion beams and cylindrical targets under HIAF-relevant beam parameters. The results show time-evolution images of specific energy deposition, temperature, pressure, and density of the target material in the radial direction during heavy-ion beam energy loading. By comparing the state of matter produced by the ion beam hitting the target at different beam energy and intensity, a interesting phenomenon is observed, i.e. a plateau region of temperature and pressure are formed near the axis center. This result indicates that under the action of the heavy-ion beam, a substantially homogeneous region is formed in the axis center the target material, further elucidating the salient characteristics of the heavy-ion beam-driven high energy density material, i.e. homogeneous state. The state parameters of the target matter undergo significant changes in the process, for a beam duration of 150 ns and a beam intensity of 4 × 1011 ppp (particle per pulse) and beam energy of 500 MeV/u. A sharp discontinuity in pressure and density occurs, forming a phenomenon known as a shock wave. Thereby, systematic modulation of heavy ion beam parameters enables investigation into the generation and propagation dynamics of shock waves. This study further constructs a systematic database that meticulously records the state parameters of target materials when uranium ion beams interact with various types of targets. The relevant simulation data provide important theoretical guidance for planning heavy-ion beam-driven high-energy density physics experiments at HIAF and crucial theoretical support for in-depth research on the generation, evolution, and properties of high-energy density matter. These advances in calculation position HIAF as a transformative platform for detecting extreme-state substances, with is of direct implications in studying inertial confinement fusion and modeling astrophysical plasma.
