Abstract : The Air Force Weapons Laboratory CHEMP code for self-consistent calculations of high-altitude electromagnetic pulse is used here to assess the energetic consequences of self-consistency, with particular attention to the alteration of the radiated electromagnetic pulse. Parametric studies indicate the sensitivity of the radiated fields to gamma spectrum, angular distribution of Compton electrons, scattering, cascading, and the reduction of radiated fields by small amounts of precursor ionization in the source region.
