Abstract: | The behavior of small samples in very short and
intense hard X-ray pulses is studied by molecular dynamics type
calculations. The main emphasis is put on the effect of various
tamper layers about the sample. This is discussed from the point of
view of structural imaging of single particles, including not only
the distortion of the structure but also the background conditions. A
detailed picture is given about the Coulomb explosion, with
explanation of the tampering mechanism. It is shown that a thin water
layer is efficient in slowing down the distortion of the atomic
structure, but it gives a significant contribution to the background. |
