Abstract

Probes are becoming widely used in fusion devices to measure edge plasma parameters. Both electrical probes and surface collector probes can provide useful data and the two techniques are largely complementary. Energy analysers are included among the electrical probes and long term probes placed on the walls for extended periods are included in the surface probes. Methods of measuring erosion and redeposition are also outlined. Some of the problems inherent in probes such as disturbance of the plasma and practical problems of construction are discussed.
