Abstract The ability to produce long-scale length (i.e. millimeter scale-length), homogeneous plasmas is of interest in studying a wide range fundamental plasma processes. We present here validated experimental platform create and diagnose uniform with density close or above the critical density. target consists polyimide tube filled an ultra low-density plastic foam where it was heated by x-rays, produced long pulse laser irradiating copper foil placed at one end tube. temperature ionized retrieved using x-ray radiography proton used verify uniformity plasma. Plasma temperatures 5–10 eV densities around 10 21 cm −3 are measured. This well-characterized for experiments large-scale platforms conducting High Energy Density Physics investigations.
