Abstract
Progress in Inertial Fusion (IF) is hampered by several plasma phenomena which limit the coupling and transport of energy into the targets. Unraveling the physics of IF target interactions is complicated by the fact that highly convoluted data are generated by the simultaneous occurrence of these plasma phenomena from a narrow spatial region. Gas jet targets offer an alternate approach to study some of the basic plasma physics of IF. The stable density profiles and relatively large spatial extent of gas jets provide experimental opportunities which are not available with conventional IF targets. The authors discuss the requirements, basic design, construction and characterization techniques for gas jet targets.
