A cryogenic hydrogen cluster-jet target is described which has been used for laser-plasma interaction studies. Major advantages of the cluster-jet are, on the one hand, the compatibility to pulsed high repetition lasers as the target is operated continuously and, on the other hand, the absence of target debris. The cluster-jet target was characterized using the Mie-scattering technique allowing to determine the cluster size and to compare the measurements with an empirical formula.

This permitted comparison of the density of the central or "void" area with that of the entire vertebra (L4), as well as with the mean value of bone at the right and left sides of the vertebral body, and with the results of both L2 and L3. The ratio-density of the center/density of the whole vertebra-was 0.
