FIG. 2.

Time evolution of plasma parameters in the T-10 tokamak during disruption at high density. Here shown: I p , plasma current; 〈n e0 〉, electron density averaged along the central vertical line; T e0 , ECE electron temperature in the plasma core; P rad , total radiated power; and I sxr , soft x-ray intensity measured using gas detectors. Magnetic perturbations are measured with the standard pickup coil (P7) and fast movable magnetic probe adjacent to the plasma periphery (MM1). Experiments indicated abrupt increase of the induced magnetic oscillations in 0.2–0.5 MHz frequency range during an energy quench (t ∼ 719.35–719.55 ms).

(a) Time evolution of the magnetic field perturbations measured with the fast movable magnetic probe (MM1) adjacent to the plasma periphery in the T-10 tokamak during energy quench at high density. (b) Fourier spectrum power density of the magnetic field perturbations. Spectrum power density is characterized by multiple spikes in the frequency range 0.2–0.5 MHz.

(a) Time evolution of the magnetic field perturbations measured with the fast movable magnetic probe (MM1) adjacent to the plasma periphery in the T-10 tokamak during energy quench at high density. (b) Contour plot of the continuous wavelet transformation coefficients for type-db4 wavelet shifted smoothly over the full domain of the analyzed function.

FIG. 5.

Radial dependence of the m = 2 mode amplitude (stars) and fast-scale magnetic field oscillations (open circles) measured using movable probe during disruption instability. Plasma with circular cross section is restrained in T-10 by graphite movable rail limiter (r RL ≈ 0.3 m) and fixed circular graphite limiter (r CL = 0.39 m). Dashed and dotted-dashed lines indicate decay of the normalized magnetic perturbations (r s /r) 3 and (r s /r) 5, accordingly.
