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. Sharma et al., Physics of Plasmas 27, 062502 (2020)</ref>. | |||
During 2021 HIBP was extended to 176 keV with a beam current up to 300 μA <ref>A. Melnikov et al., PPCF (2021) submitted</ref> | |||
The goal of this proposal is to expand the HIBP energy range [80 - 200 keV] to explore the whole TJ-II poloidal cross-section. | |||
