Figures-Two-dimensional vacuum ultraviolet images in different MHD events on the EAST tokamak

The data are from different diagnostics on the EAST tokamak.Fig.3 Spectrom analysis on Mirnov signal and VUV measurement by performing FFT calculation.Fig.4 The mode structure is derived by comparing the synthetic images and experimental data which is obtained by performing SVD analysis on the VUV images.Fig.6 Raw images captured by the VUV imaging system during an ELM crash.

Different brightness are observed at the different phases.Fig.8 Raw images captured by the VUV imaging system during an disruption. These images show the capability of the VUV imaging system on the study of MHD events on the EAST tokamak.
