Abstract
A complex electrostatic-magnetic probe diagnostics, baptized as ‘U-probe’, has been installed on COMPASS tokamak recently. Probe composes of two identical towers.
Each tower houses 3 radially spaced sets of 3D coils, triple probe and rake probe — array of six Langmuir probes. The U-probe measures electric and magnetic properties of the filamentary structures in the edge plasma, particularly the floating potential profile and local magnetic field within the plasma filaments.
Contribution presents first tests and results obtained.
