First estimations of plasma electric potential and density in URAGAN -2M (U-2M) torsatron were done by the Heavy Ion Beam Probing Diagnostic (HIBP). The estimated plasma potential has the negative potential value of -(80…195) V. The experimental values of the secondary ion beam current are well correlated with average plasma density measured by radio-interferometer - (1.25… 2.5)×10¹² cm⁻³ . Notable oscillations of the secondary beam current were observed, which were caused by fluctuations of the torsatron magnetic field.
