ABSTRACT
A heavy ion beam probe has been operated with two separate electrostatic energy analyzers to allow simultaneous detection of 2[sup +] and 3[sup +] secondary ions coming from a singly charged probing beam. This configuration provides rapid, spatially resolved measurements of the electron temperature for T[sub e] ≤200 eV, and measurements of the correlation between density and space potential fluctuations from two separate locations in the plasma. The possibility of electron temperature fluctuations can also be investigated. Since the spatial location of the measurements can be varied, the correlation length in both the k[sub r] and k[sub θ] directions can be determined.
