New Mechanism for Ion Emission in Plasma Focus Device

Summary form only given. In our experiment, high energy ions up to MeV and multiple ion emission with time period of mus were observed, also simulation (PIC code) results show, high energy ions up to MeV. In this paper for the first time we investigate the subsequent ion emission mechanism in plasma focus device. The surfatron acceleration mechanism for the multiple and high energy ion emission from the simulation result can be proposed. Finally our simulation show the ring shape of ion bunches that is good agreement with the experimental result.
