Abstract

In this report we present numerical calculations of the density profiles of neutral H, D, T, He and O in the boundary layers of a tokamak plasma. These profiles are obtained from the solution of the Boltzmann equation for the velocity distribution function. Besides the neutral components of the main plasma, H, D, and T, we have chosen to treat helium and oxygen as impurities. Helium because it has a relatively large mean free path and oxygen because it has an accidentally resonant cross-section for charge exchange with protons, deuterons and tritons. The results obtained are compared with analytical results published for some simplified cases.
