Fluctuations Measurements using Single Langmuir Probe Characteristics
It is well known that fluctuations are responsible for a significant portion of the particle loss rate in tokamaks and may account for a large part of the anomalous energy losses observed. For a complete estimate of the particle and heat transport, knowledge of the fluctuations in density, temperature and electric field are needed. However, temperature fluctuations are in general difficult to measure and then often ignored.
