description: The subject of the graduate qualification work is âInvestigation of potential oscillations in plasma during the development of Alfven oscillations using a Heavy Ion Beam Probeâ. This work is devoted to the study of Alfven oscillations using a heavy ion beam probe at the TUMAN-3M tokamak. The study of these oscillations is necessary, since they lead to instabilities that lead to the loss of highly energetic particles, which in turn worsens the heating of the plasma and poses a danger to the structural elements of the installation. The heavy ion beam probe was upgraded for the experiments. Transimpedance amplifiers with a bandwidth of 1 MHz were installed, ADCs were tuned to a clock rate of 8 MHz. A detector grid was also calculated for probing the central region of the plasma with parameters characteristic of Alfven oscillations.In a series of experiments, it was found that the heavy ion beam probe does not detect AlfvÃ©n oscillations, in contrast to probe diagnostics. By changing the probing parameters, it was found that a possible reason for the absence of oscillations in the collector plate signals is that the amplifiers do not provide a bandwidth of 1 MHz.
