dc.description.abstract© 2019 Elsevier B.V. Advanced heavy ion beam probe (HIBP) operates on the T-10 tokamak with 20–130 μA Tl+ beam accelerated up to 330 keV. The HIBP has a unique capability to measure the mean value of the core plasma potential, and the oscillations in potential φ density ne and poloidal magnetic field simultaneously in 5 spatially separated sample volumes for OH and ECRH plasmas with n¯e=(0.3−5)×1019 m−3, 100<Ipl<330 kA. Time evolution of local plasma parameters and/or radial profiles can be measured in a single shot. The profile in the range 0.25<ρ<1 is available shot by shot for B0<2.2 T. The paper describes main elements of hardware: injector, beamlines, control systems, analyzer, power supplies, and software for HIBP. Physical examples show that HIBP can measure the cross-phase of density oscillations, the poloidal phase velocity of turbulence rotation, the poloidal electric field and the radial turbulent particle flux. Spectral analysis allows us to distinguish various types of turbulence, such as broadband (<500 kHz), quasicoherent, tearing and geodesic acoustic modes.
