Abstract

The absorption of neutral beam power and the fast ion stored energy in EAST plasmas with neutral beam injection (NBI) is analyzed to improve the calculation of thermal energy confinement time. The neutral beam power absorption and fast ion stored energy are systematically calculated using the TRANSP code, through the investigation of global parameters including plasma current, line averaged density and beam energy. Results have shown that scaling laws for the NBI absorption coefficient and fast ion energy rate are obtained through statistical analysis. A comparison of the confinement improvement factor H_98y2 with these new scaling laws against those assuming fixed coefficients is given.
- thermal energy confinement time,
- neutral beam absorption,
- fast ion energy
