Quasilinear relaxation of a beam of fast ions produced in a tokamak upon injection of a beam of fast neutral atoms is investigated theoretically. Relaxation of this type is assumed to be due to interaction between the ions and Alfven waves. A beam moving along the magnetic field is considered. The shear of the magnetic force lines is neglected. It is shown that under these assumptions the quasilinear relaxation is much more rapid than the Coulomb relaxation due to pair collisions. It is concluded that the concept of a ''two-component tokamak,'' which is based on the assumption of Coulomb relaxation of the fast ions, calls in general for revision.
