Platform development for Xflows: Exposé of Radiation flows on NIF

ORAL

Abstract

The goal of the Xflows1 campaign is to bring the successful COAX2 radflow platform from OMEGA to NIF to enable studies of radiation flow in supersonic, transonic, and subsonic phases with at least two foam types. The COAX platform2-4 on OMEGA used same-shot spectroscopy and radiography to characterize the evolution of the radiation flow and developed shock, providing constraining data to radiation hydrodynamic simulations3,4. The first Xflows shot day fired a transonic halfraum and the spectroscopic (capsule) and radiography (foil) backlighters separately. In this presentation we will discuss plans to complete the development of the target in 2024 based on the data from the first shot day. The first complete target physics shot will feature transonic flow driven into a COAX-like Ti-doped foam1, with spectra collected to study radflow soon after firing the halfraum and radiography of the shock collected at later time. Finally, we will briefly overview plans to adapt the LLNL MSPEC-N spectrometer to the needs of this experimental campaign, with its first test planned for the final shot day in 2024.
