Abstract
Propagation of the various errors in a new asymmetric Abel-inversion method [Hyeon K. Park, Plasma Phys. Controlled Fusion 31, 2035 (1989)] is investigated. In order to provide a meaningful error analysis of the inversion process, both the effects of geometrical factors and measuremental errors are studied. The dominant source of uncertainty in the determination of local electron density is due to the spline fitting of the interferometric measurements with uneven spacings. The propagation of these errors is highly spatially localized and heavily damped in this inversion method. The absolute range of error in the local electron density is ±1.5×1012 cm−3.
