Production of K-shell radiation of noble gases in the microsecond implosion regime
Studies of К-shell plasma radiation sources were carried out on the GIT-12 generator (4.7 MA, 1.7 ms). In the experiments, a new type of load configuration was used to form the Z-pinch plasma - a gas puff with an outer plasma shell. Noble gases neon and argon were used as working gases. The gas puff consisted of two cascades: a hollow cylindrical shell outside and a solid jet inside. The outer plasma shell was created with the help of plasma guns located on the diameter of 350 mm. A distinctive feature of these studies is that the experiments with a plasma radiation source were carried out in the microsecond implosion mode, which usually leads to a significant decrease in the efficiency of generation of K-shell X-rays. The use of a new type of Z-pinch load has significantly improved the efficiency of the microsecond plasma radiation source. As a result of the optimization of the initial gas-puff parameters, the neon K-shell radiation yield of 14.7 kJ/cm at a peak implosion current of 3.5 MA was achieved. In experiments with argon gas puffs, the radiation yield reached 1.9 kJ/cm at a peak implosion current of 3.1 MA.
