Interaction of intense femtosecond laser pulses with iron clusters formed by photo-dissociation of Fe(CO)5

The experimental results of investigation of X-ray radiation provided by interaction of intense femtosecond laser pulses with Fe-clusters are presented. A new method of iron particles formation at room temperature by the photo-dissociation of Fe(CO)5 vapor is applied. The X-ray radiation was studied using photodiodes and high efficiency focusing crystal von Hamos spectrometer with a CCD linear array as X-ray detector. The results of investigation of clusters formation, spectral measurements in photon energy range E=1÷13 keV and estimation of X-ray radiation yield are presented.
