Gasoline spray imaging by polycapillary X-ray technique

First use of a Cu X-ray source in combination with polycapillary halflens (or semilens) and a Photonic Science CCD detector for investigating highly dense jet injection sprays are reported. It is shown that in the energy range used the absorption signal is above the background level indicating but interaction of the beam with the fuel is weak. These preliminary results offers new research opportunities within various Italian research centers.
