Structure of MHD fluctuations in the torsatron U-3M in steady-state stage of discharge
Study of MHD fluctuations was performed in quasi-stationary mode of weakly collisional discharge in torsatron U-3M in frequency range 0.5…70 kHz. The fluctuations of the magnetic field were detected in the following frequency ranges: 2.5…3.9, 5.9…7.2, 9.4…10.9, 14…15.9, 20…27, 39…47 kHz. It is als...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Study of MHD fluctuations was performed in quasi-stationary mode of weakly collisional discharge in torsatron
U-3M in frequency range 0.5…70 kHz. The fluctuations of the magnetic field were detected in the following frequency
ranges: 2.5…3.9, 5.9…7.2, 9.4…10.9, 14…15.9, 20…27, 39…47 kHz. It is also shown that there are standing and
rotation structures. Rotation structures can rotate in the direction of both ion and electron diamagnetic drift. The
poloidal structure of plasma MHD activity with wave numbers m=0; 1; 2; 3 was obtained, which made it possible to
determine the level of fluctuations of the magnetic field inside the confinement volume. |
