It is demonstrated how femtosecond plasma X-ray sources can be used to record X-ray diffraction images with many simultaneous reflections. A convergent-beam geometry was implemented and tested with a crystal of a small molecule [Fe-py3(tren)] as well as with a crystal of the protein lysozyme. The results pave the way for femtosecond X-ray crystallography.
