Abstract: | The feasibility of attaining a short-pulse-duration heavy ion beam with a nanosecond pulse length is studied in the main ring of the Heavy Ion Research Facility in Lanzhou(HIRFL).Such a heavy ion beam can be produced by non-adiabatic compression,and it is implemented by fast rotation in the longitudinal phase space.In this paper,the possible beam parameters during longitudinal bunch compression are studied by using the envelope model.The result shows that a shortest heavy ion bunch 238U28+ of 29 ns with energy of 200 MeV/u can be obtained,which can satisfy high energy density physics research. |
