New fields of x-ray sources applications (x-ray laser and High Order Harmonic Generation) could appear if an intensity higher than 1012 Wcm-2 is reached. Following this goal, we have started a complete investigation of the x-ray beam wavefront both numerically and experimentally. The first xuv wavefront sensor has been developed and tested on different xuv sources For a better comprehension of the experimental results, a numerical work (ray-trace code) has been performed meanwhile. We will present and discuss the first results obtained on the x-ray laser at 21.2 nm.
