Efficiency of current drive by pulsed injection of REB
Description
A simple analysis based on a relativistic kinetic equation for relativistic electron beam (REB) dynamics combined with a set of circuit equations is performed for evaluating the efficiency of a current drive by a pulsed REB. A two-dimensional numerical result is given for the efficiency as wells 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 efficiency is given. Optimization for the REB current drive in a reactor-grade tokamak is discussed. (author)
