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 fp. At small fp, 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 fp, which accorded with the finding that the probability of vortex to be pinned increased with fp. Some of our results agreed with experimental findings.
