Abstract : Starting from the expression for the cooperative ionization energy loss by a pair of relativistic particles, a formula is derived for the beamdensity effect on ionization energy loss for a finite length beam with a Gaussian radial profile. As an example, this formula is evaluated for a 50 MeV, 10 KA electron pulse of one meter length interacting with weakly ionized nitrogen. In this case a large beamdensity effect on energy loss was obtained and its dependence on the ionization state of the medium was demonstrated. The relationship of this formulation of energy loss with previous singleparticle and beamplasma loss concepts is discussed. (Author)
