Recent experiments at Cornell have been performed to investigate X‐pinch plasmas as intense x‐ray sources which might be used to pump resonant photoexcitation lasers. Crossed Al wires have been driven by up to 600 kA current for 40 ns. High density bright spots are observed at the crossing point(s). Various diagnostics were used to characterize the X‐pinch plasmas as a function of initial mass loading for several specific wire configurations. The optimum mass loading for different ionization stages of Al, and the total x‐ray energy yields, which are on the order of hundreds of Joules, were examined. Estimates of plasma density, ∼1020 cm−3, and temperature, about 400 eV, were obtained. |
