Selina-Jane Spencer: Inflationary Stimulated Raman Scattering (iSRS) in inhomogenous plasmas
Abstract: In this work we take as a starting point the extensive literature on iSRS in homogeneous plasmas for indirect-drive ICF, and use PIC simulations to probe how iSRS develops in plasmas with a density gradient, such as those that will be present in shock-ignition direct-drive ICF schemes. In this talk, we will present results of the first simulations of iSRS in inhomogeneous plasmas with NIF-relevant parameters and scale-lengths. An increased understanding of the link between coronal density scale-lengths and reflectivity due to SRS and iSRS is of significant interest to the development of shock-ignition ICF schemes.
