Beschreibungen/Notizen

• In the MagLIF ICF scheme, a cylindrical gas volume is laser heated before the walls of the cylinder are driven radially inward to compress the heated gas. Exploring the effects of material from the walls and the laser entrance window mixing into the heated region are important considerations for MagLIF experiments 1 , 2 , 3 ,. The addition of these materials into the heated gas can potentially have detrimental effects, radiatively cooling the gas fill and degrading the yield 4 . The NIF has been used to drive gas-pipe experiments where a tracer element (Ti) is placed on the LEH window or where strips of Ti and Sc are attached to the wall. Spatially and temporally resolved spectroscopic measurements of the Ti and Sc emission indicate the spatial location of these materials at various times during the interaction, assisting future predictions and mitigations of their propagation into the gas-pipe.
