Abstract :
We have measured the increase of the spatial coherence with plasma column length in a table-top capillary discharge pumped 46.9 nm Ne-like Ar soft X-ray amplifier for lengths up to 16.4 cm. These results, which are in good agreement with wave-optics model computations, provide the first experimental evidence of a monotonic build up of the spatial coherence with plasma column length in a soft X-ray amplifier. The variation of the coherence across the beam profile was also studied
