摘要: We demonstrate the combination of fast-ion D-alpha spectroscopy (FIDA) and collective Thomson scattering (CTS) measurements to determine a common best estimate velocity distribution function by velocity-space tomography. further benchmark FIDA tomography CTS without using numerical simulation as reference. Combined tomographies from confirm that sawtooth crashes reduce phase-space densities in plasma center affect ions with pitches close one more strongly than those zero.
