We examine the use of Derbenev's helical sweeping method to reduce the energy spread of a
muon beam. We briefly review the basic theory behind the sweeping method and describe the
modeling of the magnetic fields in ICOOL. We discuss the efficiency of the method for
producing dispersion and for removing energy spread in the beam. We consider the deleterious
effects of stochastic processes and finite transverse emittance. Unfortunately, we find that this
method is not useful for reducing the energy spread of the beam produced from the neutrino
factory target.
