Comparison of Langmuir probe and Thomson scattering measurements of electron temperature and density
Abstract
Measurements of electron temperature and density made with Langmuir probes are compared to those made by Thomson scattering. The comparison is made over a range of electron density [(0.3-1.6)×1015 cm-3] and temperature (1-2 eV). The two diagnostic techniques agree to within 20% in the case of the electron temperature and to within 10% in the case of the electron density.
