Abstract

A calibrated x-ray spectrometer was used to characterize an intense 4.5 keV K_α source. Generated from the interaction of 30 J-320 fs laser pulses focused on 25 μm thick Ti foils, the conversion efficiency into Ti K_α line is estimated to (9±6) × 10-5. Highly efficient collection, monochromatization and focusing were achieved using an ellipsoidally bent highly oriented pyrolytic graphite crystal. The measured 700 μm full width half maximum (FWHM) focal spot leads to a fluence of (3.0±2.1) mJ/ cm² hence paving the way to the study of intense x-ray pulse interaction with matter as demonstrated by a first simple experiment.
