Experiments with aluminium wire array Z-pinches have been carried out on the MAGPIE generator (1MA, 240ns) at Imperial College London. It has been shown that in these arrays there are two intense sources of radiation during stagnation: line emission from a precursor-sized object and continuum radiation from bright-spots of significantly higher temperature randomly distributed around this object such as to produce a hollow emission profile. Spatially resolved spectra produced by spherically-bent crystals were recorded, both time-integrated and time-resolved, and were used to show that these two sources of radiation peak at the same time.
