Metal puff Z pinch allows to study many phenomenon related to the Z pinch implosion. In this type of system, the Z pinch is produced by plasma guns. Each gun initiates a vacuum arc operating between metal electrodes. The electric circuit permits to vary independently the linear mass of the inner jet and outer shells. We found that the linear mass is the function of the gun current and gun current density. The linear mass varied from 10 up to 80 μg/cm. This study presents the experiments with Mg and Bi metal puff. The IMRI-5 generator was used as a z-pinch driver. The generator produced a damped sinusoidal current pulse of amplitude 450 kA with a 450-ns quarter period rise time. During the study we varied the ratio between the mass of the inner jet and the outer shell and found the 0.5 ratio that is the optimal from the point of view the maximal compression. Mg K-shell yield was five times more that the yield estimated according to MKQ model. At the implosion of Bi solid-on-jet the total radiation energy is equal to 16% of the capacitor bank energy.
