description: This work is devoted to the study of plasma and radial electric potential oscillations using a diagnostic beam of heavy ions on the TUMAN-3M tokamak during coinjection of a heating beam, as well as during the development of Alfven oscillations. Studying the potential allows us to better understand the mechanism of transition to the improved confinement mode, as well as the influence of co-injection on this. Alfven oscillations lead to losses of energetic particles, which can impair plasma heating, so their study is an important task. To carry out the experiments, the neutral beam injection scheme was changed. In the experiments presented in this work, the beam was injected in the direction of the plasma current. Using HIBP, measurements of the plasma potential and radial electric field were carried out in the ohmic mode, the mode with co-injection of the heating beam and with additional gas injection. In experiments studying Alfven oscillations, they were not detected in HIBP signals. The localization of these oscillations was indirectly calculated.
