In this paper, results from the array of fixed Langmuir probes in the JET Mark 1 divertor are presented. During low density discharges there is good agreement between single and triple probes. At higher density, near the onset of divertor detachment, very low values of the electron to ion saturatio

β¦ Synopsis
In this paper, the array of Langmuir probes at the COMPASS-D divertor and the analysis and interpretation of the probe data are described. The divertor probe system consists of 39 graphite single Langmuir probes embedded in the divertor target. The probe array is being used to investigate the properties of the divertor plasma on COMPASS-D single-null X-point discharges; its high spatial and temporal resolutions allow a detailed study of a variety of fast phenomena such as fluctuations and ELMs. Results on these topics are also presented.

## Abstract In order to investigate details of anomaly in the Langmuir probe current (I)βvoltage (V) characteristics, electron temperatures and densities are measured by both Langmuir probe and laser Thomson scattering methods. The electron densities measured with both methods show good agreement i
