First results of magnetic turbulence measurements using an array of Hall detectors in the TEXTOR tokamak

Hall detectors were used to measure the magnetic field B together with it's fluctuations in the boundary of the TEXTOR tokamak. The results showed that such measurements, performed so far mainly by the use of coils, can be substituted by Hall probe measurements, which yield the magnitude of B directly. Because the integration of the coil signal becomes more and more difficult for longer discharges, Hall detectors may prove advantageous in future fusion devices.
