Numerical calculation of high frequency fast wave current drive in a reactor grade tokamak
- 1. Japan Atomic Energy Research Inst., Naka, Ibaraki. Naka Fusion Research Establishment
Description
A fast wave current drive with a high frequency is estimated for a reactor grade tokamak by the ray tracing and the quasi-linear Fokker-Planck calculations with an assumption of single path absorption. The fast wave can drive RF current with the drive efficiency of ηCD = n-bare(1019 m-3)IRC(A)R(m)/PRF(W) ∼ 3.0 when the wave frequency is selected to be f/fci > 7. A sharp wave spectrum and a <υph||>/υTe ∼ 3.0 are required to obtain a good efficiency. A center peaked RF current profile can be formed with an appropriate wave spectrum even in the high temperature plasma. (author)
