A method for determining the fast-ion population density in magnetically confined plasmas as a function of pitch-radius, (λ, R), using a
solid-state neutral-particle analyzer (ssNPA) signal and neutral-beam injection (NBI) power-output data has been developed. Oscillations in
the NBI power output are replicated only in the active part of the ssN…
A method for determining the fast-ion population density in magnetically-confined plasmas as a function of radius-pitch values, (R, Lambda), using ssNPA-signal and NBI power-output data has been developed. Oscillations in the NBI power output are replicated only in the active part of the ssNPA signal, allowing this to be separated…
