An analytical model of how the negative triangularity cuts off the access to the second stable region in tokamak plasmas

Nuclear Fusion
We present an analytical model to evaluate the triangularity-shaping effects in accessing the second stable region for the ideal ballooning mode. Our results indicate that if the triangularity is sufficiently negative, the path from the first to the ...

Experimental scaling of compressional Alfvén eigenmode stability

Nuclear Fusion
Both co-propagating and counter-propagating compressional Alfvén eigenmodes (CAE) are relatively ubiquitous in NSTX plasmas with toroidal field strengths of ⩽4.65 kG, but are largely absent in the NSTX-U plasmas with toroidal fields of 5.7–5.9 kG.
