Confinement parameters, ntau, are calculated for several possible magnetically-confined p-/sup 11/B reactor configurations using a computer code that evaluates cyclotron radiation emission by electrons and follows the energy distributions of the reactants and products explicitly as they undergo nuclear reactions and both low and high angle scattering. The present treatment of cyclotron radiation assumes a uniform magnetic field and an isotropic plasma. Reflectivity is included as an input parameter. The influence of cyclotron radiation on the energy balance of the various p-/sup 11/B reactor configurations is evaluated and the deviation of the electron distribution from a Maxwellian due to cyclotron radiation emission is studied.
