© EPS 2019. All rights reserved.Plasma density turbulence (f < 250 kHz) study using 5-slits HIBP in ohmic T-10 discharges (Bt = 2.2-2.48 T, Ipl = 200-230 kA, ne = 1-3×1019 m-3) have shown the complex frequency and spatial structure. It was shown that SLF and LFQC modes have features of solitary bursts with poloidal wavelengths comparable to correlation lengths (?cor SLF ˜ 4 cm, ?cor LFQC ˜ 5 cm, ?SLF < 20 cm, ?LFQC < 7 cm). LFQC always rotates to the EDD direction, while SLF may also rotate to the IDD direction. Study of these differences is a topic for further research.
