Abstract
The conceptual design of a Heavy Ion Beam Probe (HIBP) diagnostics has been developed for ITER by international HIBP workgroup aiming to contribute for: (i) understanding of the H-mode and Advanced Tokamak mode by the measurement of the plasma potential profile, which allows to monitor and control the electric field at the plasma edge; (ii) the accurate investigation of the plasma edge by simultaneous determination of the plasma potential density and poloidal magnetic field profiles and fluctuations; and (iii) the study of new mechanisms of plasma rotation in ignited plasmas such as losses of alpha particles. In comparison with the traditional scheme this design presents the innovative modification — the electrostatic bending system for primary and secondary beams aiming to transfer them throw the strong B-field area. The estimation of the energy range, beam attenuation and the cost lead to the conclusion that proposed project could make HIBP a realistic diagnostics for ITER.
