Description

A simple analysis based on a relativistic Fokker-Planck equation for relativistic electron beam (REB) dynamics combined with a set of circuit equations is performed for evaluating the efficiency of current drive by a pulsed REB. A more accurate numerical result is given for the efficiency as well as for the temporal evolutions of the REB momentum distribution function and the circuit quantities. A comparison of the numerical result with the analytical limit for the efficiency is given. Optimization for the REB current drive in a reactor-grade tokamak is discussed. (author)
