## When low photon energy ranges (3-40 keV1 are required in a synchrotron beamline, the use of beryllium windows to isolate the machine vacuum from the beamline is forbidden. In addition, if the operating pressure of the beamline is three orders of magnitude larger that of the machine, the only way
