Earlier ablative imprint studies describe how to infer the X-ray beam profile from the damage that an attenuated beam inflicts on a substrate. However, the beams in-situ profile is not directly accessible with imprint studies because the damage profile could be different from the actual beam profile. On the other hand, although a Shack-Hartmann sensor is capable of in-situ profiling, its lenses may be quickly damaged at the intense focus of hard X-ray FEL beams. We describe a new approach that probes the in-situ morphology of the intense FEL focus. By studying the translations in diffraction patterns from an ensemble of randomly injected sub-micron latex spheres, we were able to determine the non-Gaussian nature of the intense FEL beam at the Linac Coherent Light Source (SLAC National Laboratory) near the FEL focus. We discuss an experimental application of such a beam-profiling technique, and the limitations we need to overcome before it can be widely applied. 000151996 536__ $$0G:(DE-H253)POF2-XFEL-in-house-20130405$$aXFEL In-house research / external facilities (POF2-54G17)$$cPOF2-54G17$$fPOF II$$x0 000151996 536__ $$0G:(DE-H253)POF2-CFEL-Exp.-20130405$$aExperiments at CFEL (POF2-544)$$cPOF2-544$$fPOF II$$x1 000151996 693__ $$0EXP:(DE-MLZ)External-20140101$$5EXP:(DE-MLZ)External-20140101$$eMeasurement at external facility$$x0 000151996 693__ $$0EXP:(DE-H253)CFEL-Exp-20150101$$5EXP:(DE-H253)CFEL-Exp-20150101$$eExperiments at CFEL$$x1 000151996 7001_ $$0P:(DE-H253)PIP1009124$$aStarodub, D.$$b1 000151996 7001_ $$0P:(DE-H253)PIP1008257$$aLomb, L.$$b2 000151996 7001_ $$aHampton, C.
