  We investigate the scaling behavior of a very large magneto-optical trap
(VLMOT) containing up to $1.4 \times 10^{11}$ Rb$^{87}$ atoms. By varying the
diameter of the trapping beams, we are able to change the number of trapped
atoms by more than 5 orders of magnitude. We then study the scaling laws of the
loading and size of the VLMOT, and analyze the shape of the density profile in
this regime where the Coulomb-like, light-mediated repulsive interaction
between atoms is expected to play an important role.
