A flash X-ray device dedicated to diagnostic of fuel injection sprays has been developped, tested and improved. Considering the absence of electromagnetic focal system for the electron beam, an important reduction of the X-ray emission zone has been achieved (from 3mm to ~150µm) thanks to carbon fiber cathodes. A full energy characterization, in the range [5, 40] keV, has been made with coplanar Germanium detector for 4 types metallic anodes: Fe, Cu, Mo, W.
