Assessment of 0-D L-H Power Threshold Scaling and Regression Stability in DIII-D with Applied 3D Magnetic Fields
Michael O Hanson, George R Tynan, Dmitri M Orlov
A database of 192 L-H transitions in DIII-D is used to assess the effects of applied three-dimensional (3D) magnetic fields on the H-mode power threshold and the stability of zero-…

Effect of Controlled Magnetic Island Bifurcation on Electron Diffusion
Jessica Eskew, D. M. Orlov, B. Andrew +7
Magnetic islands strongly influence cross-field electron transport in magnetized plasmas. In particular, bifurcations of the island topology modify the number and location of O-poi…
