  Comparing quantities to analyze charged fluctuations in heavy ion experiments
the dispersion of the charges in a central rapidity box was found to be best
suited. Various energies and different nuclear sizes are considered in an
explicit Dual-Parton-Model calculation using the DPMJET code and a randomized
modification to simulated charge equilibrium. For large enough detection
regions charged particle fluctuations can provide a signal of the basic
dynamics of heavy ion processes.
