Tearing Modes – nonlinear growth
{"Image DocumentName": "Tearing Modes \u2013 nonlinear growth", "Image ImageDescription": "Interpretation of the different terms. for small \uf0d1p, current gradient ( ) dominates \uf0de classical Tearing Mode , current driven. (most of the time stable except if q profile is tweaked , which is why resistive MHD was never a big thing up to end 1990s for tokamak interpretation) for larger \uf0d1p, pressure gradient dominates: \uf0de neoclassical Tearing Mode , pressure driven. adding an externally driven helical current can stabilise. 3D MHD simulations show that full non-linear NTM is more complicated. Inner layer much larger than expected. Outer and inner layers cannot be realy separated. Analysing 3D MHD saturated mode and MRE can lead to large differences.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
