Abstract: The properties of a two-dimensional vortex system with random columnar defects were studied by cooling the vortex system to zero temperature. The vortex lattice became more and more disordered with increasing pinning strength f_p. At small f_p, a triangular vortex lattice away from the pins was observed. The peak of structure factor S(G₀) of the vortex lattice decreased with pinning strength f_p, which accorded with the finding that the probability of vortex to be pinned increased with f_p. Some of our results agreed with experimental findings.

Key words: vortex lattice(VL), columnar defects, structure factor
