The development of new diagnostics is important to improve the interpretation of experiments. Often well-known physical processes and techniques originally developed in unrelated fields of science can be applied to a different area with a significant impact on the quality of the produced data. X-ray phase-contrast imaging (XPCI) is one techniques which has found many applications in biology and medicine. This is due to its capability to emphasise the presence of strong density variations normally oriented with respect to the X-ray propagation direction.

This work is concerned with both theoretical studies and the experimental developments of a plasma device to be used in plasma-based accelerators. In the field of the particle accelerators is growing the interest in the development of compact accelerator machines that also have to be able to exceed the current limits of the conventional accelerator structures. This research activity is leading towards plasma-based devices able to produce accelerating gradients in the GV/m scale.
