The effect of the bumpiness of the longitudinal magnetic field of a tokamak on the confinement of high-energy ..cap alpha.. particles produced in the fusion reaction is studied. It is found that the bumpiness can lead to a collisionless escape of ..cap alpha.. particles produced with small longitudinal velocities. A general equation is found for the flux density of these particles to the wall of the tokamak chamber. This equation is used to analyze the distribution of the ..cap alpha.. flux to the chamber wall and to estimate the magnitude of this flux for tokamaks with various degrees of bumpiness. Most of the numerical estimates are carried out for the T-20 tokamak, currently being planned.
