The influence of anode/target ion species on the magnetically immersed.
- ATK Mission Research, Albuquerque, NM
The magnetically immersed (B{sub z}) diode is being investigated as a source for pulsed-power driven flash radiography. Experiments fielding this diode have revealed a limit on its achievable current density on target. Either a small spot produces a low dose, or a high dose is achieved with a large spot. It has been proposed that this limit is due to non-protonic ions liberated from the anode surface and subsequently ionizing to higher states. The three-dimensional particle-in-cell code LSP is used to investigate this proposal. Data from the recent immersed diode experiments conducted on the RITS-3 accelerator are compared to LSP models of the experimental configuration, including the B{sub z} field map. We report on how the non-protonic and protonic ion models compare to data, and proposals for future investigation.
