The goal of the Plasma Liner Experiment (PLX) is to explore and demonstrate the feasibility of forming imploding spherical 'plasma liners' via merging high Mach number plasma jets to reach peak liner pressures of ∼0.1 Mbar using ∼1.5 MJ of initial stored energy. Such a system would provide HED plasmas for a variety of fundamental HEDLP, laboratory astrophysics, and materials science studies, as well as a platform for experimental validation of rad-hydro and rad-MHD simulations. It could also prove attractive as a potential standoff driver for magnetoinertial fusion. Predicted parameters from jet formation to liner stagnation cover a large range of plasma density and temperature, varying from ni∼1016 cm-3, Te≈Ti∼1 eV at the plasma gun mouth to ni>1019 cm-3, Te≈Ti∼0.5 keV at stagnation. This presents a challenging problem for the plasma diagnostics suite which will be discussed.
