The first experiments aimed at obtaining the 2D distribution of plasma potential were performed in TJ-II using Heavy Ion Beam Probe (HIBP) with the variation of two parameters: plasma entrance angle and the energy of the Cs+ probing beam in the range 128-148 keV <ref>R.

The goal of this proposal is to expand the HIBP energy range [80 - 200 keV] to explore the whole TJ-II poloidal cross-section. | The goal of this proposal is to expand the HIBP energy range [80 - 200 keV] to explore the whole TJ-II poloidal cross-section. | ||
