Abstract
Heavy Ion Beam Probe (HIBP) is a unique tool for investigating the electrical potential and various turbulence characteristics in both the core and edge of toroidal plasmas. The position of the HIBP measurement region is defined by the energy of the probing beam and the entrance angle into the plasma. The probing beam energy is constant during the plasma discharge, and it determines the maximum penetration depth of the beam into the plasma. The entrance angle can be varied during one discharge, and the positions of the measuring points for different beam angles can be set as a detection line. The set of detector lines for different probing beam energies represents a two-dimensional region (detector grid) in the vertical plasma cross section. The paper presents a method of data processing, which allows us to build two-dimensional distributions of plasma parameters from HIBP data in the T-10 tokamak using the electric potential of the plasma as an example.
