“…The n = 19-n = 18 transitions were observed with enough intenisty that, by averaging the data from six discharges, the time evolution of these iron ions could be measured with satisfactory accuracy for determining the transport coefficients. The measured spatial distributions are compared in figure 17 with calculations from the MIST code (Hulse 1983) in which a radially varying diffusion coefficient increasing from 1.3 m2 s-' on-axis to 2.4 mz s-' at the edge is assumed.…”

Charge-exchange spectroscopy in fusion plasmas entails the use of optical transitions that follow electron transfer from a neutral atom into an excited state of an impurity ion. In most applications, the sources of neutral particles are high-energy beams employed either for heating or for the specific purpose of active plasma diagnosis. The transitions following charge exchnge are particularly useful for determining the densities of fully stripped low-2 ions and for measuring ion temperdtUKS and plasma rotation, although they have alm been exploited for other purposes. In this rebiew, the atomic physics considerations for interpreting the data, including the influence of the plasma environment, are reviewed, and examples of recent applications to fusion studies are presented.
