摘要

For a muon-decay neutrino beam facility,such as the long-baseline neutrino factory(NF)and the medium-baseline MOMENT(MuOn-decay MEdium-baseline NeuTrino beam facility),the requirement of high intensity muon source requires that the target station be capable of surviving with the bombardment of a proton beam with multi-even tens-of-MW power.The high beam power and the small target size lead to an extremely high power density,which poses significant challenges to the target station.For the NF,it is believed that the mercury jet target can handle the power deposition of a 4 MW proton beam.However,the temperature will not be much lower than the boiling point of mercury(~357℃).
