X-ray pulse stretching after diffraction

Popis výsledku v původním jazyce

The development of ultra-short X-ray pulse sources requires an optics that keeps the pulse length as short as possible. One source of pulse stretching is the penetration of the pulse into a crystal during diffraction. Another source is the inclination of the intensity front when the diffraction is asymmetric. Currently, the theory of short X-ray pulses diffraction is well developed by many authors. As it is rather complicated, it is sometimes difficult to foresee the pulse behavior (mainly stretching) during diffraction on various crystal arrangements. In this paper, a simple model is suggested that gives a qualitatively similar shape of the diffracted pulse which follows from exact theory. It allows proposing what experimental arrangement is optimal to minimize the pulse stretching during diffraction. The effect of pulse stretching due to penetration into a crystal surface is studied. On basis of this, the pulse profile change during the diffraction on two crystals, is predicted.
