Interaction of e-beams with tantalum foils and Ta/sub 2/O/sub 5/ foam

Summary form only given. We present recent progress of the study of interaction of an e-beam with tantalum foils and Ta/sub 2/O/sub 5/ foam. (1) Simulations on ETA-II target experiments. To study the hydro characteristics of beam foil interactions, a series of experiments were performed on ETA-II. The experiments were performed using different focal spot sizes to study different energy densities. Hydro-simulations performed using LASNEX to model these experiments and comparison with experimental results are discussed. (2) Linking LASNEX with MCNP. The latest code modification allows us to link simulation data between LASNEX and MCNP automatically and consequently the time required for the multi-pulse target simulation is reduced and the accuracy of simulation is improved. The physics of foil expansion caused by beam heating and the effect of a multi pulse is discussed.
