Experimental results are presented of a novel [ital Z]-pinch configuration in which two concentric columns of an initial, partially ionized plasma are compressed. Experimental comparison with the laser initiated gas embedded [ital Z] pinch and with the microdischarge initiated dense [ital Z] pinch performed on the same generator shows that the new configuration exhibits axial compression and no macroscopic instabilities are observed. A maximum current of 130 kA is obtained for a discharge in hydrogen at 0.33 atm. On axis electron density, [ital n][sub [ital e]] of 3[times]10[sup 25] m[sup [minus]3], is observed 110 ns after the initiation of the discharge, 20 times larger than the laser initiated gas embedded [ital Z] pinch.
