Pellet cloud expansion in JET
The 2.0x1020D pellet is injected from the outer midplane into the plasma which is very unstable already without the pellet perturbation. The density contour plot is plotted at the separatrix. The localized ballooning mode structures appear along the magnetic field lines which are at the pellet cloud (pink band).
