At the time of the X-ray pulse a fraction of the total current remains in a low density trailing plasma surrounding the stagnated plasma column. The corresponding reduction of the magnetic energy delivered to the radiating pinch affects the radiation power. In a model presented in this paper we assume that the division of current between the pinch and the trailing mass is controlled by the onset of ion acoustic turbulence in the trailing plasma. We will discuss the scaling of the radiation power with the amplitude and rise-time of the current, with array diameter and mass predicted by the model, and compare predictions with experimental data from the Z facility.
