Abstract: | In most collisional schemes of x-ray laser (XRL) experiments, a
bow-like intensity distribution of XRL is often observed, and it is
generally ascribed to the two-dimensional hydrodynamic behaviour of
expanding plasma. In order to better understand its essence in
physics, a newly developed two-dimensional non-equilibrium radiation
hydrodynamic code XRL2D is used to simulate a quasi-steady state
Ni-like Ag XRL experiment on ShenGuang-II facility. The simulation
results show that the bow-like distribution of Ni-like ions caused by
over-ionization in the central area of plasma is responsible for the
bow-like shape of the XRL intensity distribution observed. |
