Dynamics of tensile pressure in ion beam heated matter applied to a liquid lithium production target for the Super-FRS at FAIR

The integrity of the liquid lithium jet after pulsed ion beam irradiation is investigated by means of three-dimensional hydrodynamic simulations combined with an analytical analysis of the target response. It is predicted that for the desired beam intensity the heated target will be destroyed due to spallation and following fragmentation of the heated matter. The stability of the liquid lithium jet after ion beam heating is a crucial question for design of the fragment separator Super-FRS, which will be a part of the new FAIR facility at GSI.
