The solution to the BFKL equation grows like a power of center of mass energy, s, violating unitarity conditions at high energies. The growth of the cross section can be tamed by taking into account multiple pomeron exchanges. This is known as saturation and it is expressed in the Balitsky-Kovchegov equation. Conservation of energy should also slow down the growth of the cross section, and our aim in this work is to study the effects of enforcing energy conservation in DIS-events. Using the dipole picture, onium-onium collisions can be viewed, in the large Nc and the leading logarithmic limits, as the scattering of a collection of color dipoles. We construct a Monte Carlo program, based on Mueller's model and using energy conservation, to study onium-onium and onium-nucleus collisions. Dipole fusion processes will be important at high gluon densities and should also slow down the growth of the cross section. We propose an expression for the fusion factor and use it in our Monte Carlo to study its effects.
