Abstract
- We studied the explosive evaporation of high energy density matter generated by irradiation of intense heavy ion beams and the resulting effect on the dynamic vacuum of the accelerator beamlines. High Energy Density Physics (HEDP) experiments are proposed at the plasma physics terminal at the Facility of Antiproton and Ion Research (FAIR), which is currently under construction. The target response to irradiation by intense beam was simulated by HEIGHTS (High Energy Interaction with General Heterogeneous Target Systems) simulation package. The vacuum deterioration resulting from the target evaporation was simulated with the Molflow+ Monte-Carlo simulator. Experimentally we measured the pressure wave propagation at the HTD beamline at GSI in order to benchmark the simulation. The pressure wave was generated through ohmic heating of a cold surface.
