Brillouin backscatter model in LASNEX: improvements and additions
Technical Report
·
OSTI ID:6649074
In the 1978 Annual Report, a stimulated Brillouin scatter (SBS) model for LASNEX was described. Many improvements and additions have been made in 1979 in order to model the Brillouin backscatter in underdense plasmas more accurately. The density dependence of the model was changed and the effects of inhomogeneous media were included. A self-consistent calculation of the hot ion contribution to the ion damping was added and the saturation calculation and calculation of backscatter when a very small fraction is reflected were improved. Finally, the treatment of the backscattered light has been considerably expanded. In this report, these changes to the SBS model are described.
