Numerical investigation of targets for ion driver energy ∼100 kJ:: Some effects of ion stopping and energy deposition in cold and plasma targets

Target behavior under the impact of ∼100 kJ 20–200 ns ion pulses is investigated. Beam parameters are close to the expected parameters of TWAC–ITEP and SIS upgrade accelerators. The influence of spot size and shape on inner region compression is studied for carbon, gold, gold+DT, etc. cylindrical targets. Hydro and thermal properties of targets are investigated for different pulse shapes and durations. The numerical results on modeling of possible experiments on TWAC-ITEP and SIS+Phelix facilities are discussed. Fundamental properties of beam–matter interaction, such as total ion stopping range and energy deposition, strongly affect target behavior under the impact of ion beams. These effects are discussed in the report.
