abstract = {Measurement performance assessment has been carried out for
the latest design of the ITER Charge Exchange Recombination
Spectroscopy (CXRS) Edge diagnostic system. Several plasma
scenarios, covering all expected baseline operation regimes
for ITER, were used. Various impurity (He, Be, C, and Ne)
concentrations for the system whole spatial range (0.5 < r/a
< 1.0) were considered. Statistical errors for the
measurements of low-Z impurity temperature, density, and
rotation velocity were calculated. Other non-statistical
error sources were reviewed, including the presence of wall
reflections, effects on the active charge-exchange line
shape, calibration, and positioning uncertainties. Minimal
impurity concentrations, allowing measurements with required
accuracy, were obtained. It was shown that the CXRS Edge
system will be able to measure primary plasma parameters
with required accuracy, space, and time resolution},
