Numerical study on effects of secondary electrons generated by TEMP II accelerator

A pulsed voltage of magnetically insulated diode and intense pulsed ion beam (IPIB) models have been built according to the experimental results. A model of secondary electrons yield while IPIB irradiated metal target has also been established. The temporal law of secondary electrons induced by IPIB irradiated titanium target according to the energy deposition at surface layer has been calculated based on the models. The maximum number of secondary electrons reached is 1013/cm2 while the energy density of IPIB is 4 J/cm2. And near the surface of target, the electric field rises up to 1010 V/m with the same IPIB energy density irradiation. The evaporation ions will be accelerated near the target, therefore it is important to the formation of films.
