We find a strong volume dependence of the position of the critical end point. In the large volume limit we obtain\ T^E/T_c approximately 0.95 and mu_B^E/T^E approximately 1.1, where T_c is the cross over temperature at zero chemical potential, and T^E and mu_B^E are the temperature and the baryon chemical potential at the critical end point. The small value of mu_B^E places it in the range of observability in energy scans at the RHIC.6 pages, Contribution to LATTICE 2005 (Non-zero temperature and density)High Energy Physics - Latticetext
