Features of heavy ion beam probe application to stellarator-like devices have been connected with specific stellarator characteristics: zero (negligible) plasma current, relatively high poloidal and stray magnetic fields, toroidal asymmetry of magnetic surfaces and various operational regimes connected with different magnetic configurations. This paper shows how to decrease the errors in HIBP measurements due to these disadvantages. Absence of the plasma current in stellaratorlike devices gives possibility to make secondary ion beam energy analyzer calibration in situ in each plasma shot. This advantage improves accuracy of plasma potential measurements by HIBP diagnostic on TJ-II stellarator.
