A ollision between cold and rarefied aluminium plasma with a dense and hot aluminium plasma is experimentally investigated. Both plasma clouds are produced by the same laser pulse impinging on a specially designed ablation target. The collision region is studied by XUV time resolved photography and spectroscopy. Soon after the two plasma clouds come into touch, a dense and stationary collision zone is formed in the space between the two targets. This collision zone by far outlives both plasma clouds that have created it. XUV spectroscopy indicates slower cooling of the collision zone, but more work with different target materials is needed to see if it is possible to generate X‐ray laser emission this way.
