Available in PDF, EPUB and Kindle. Book excerpt: Contributions were made towards the ultimate goal of creating a complete theory of edge turbulence and transport in magnetic fusion devices. The main focus has been to utilize a resistive MHD model. This analysis includes: (1) rippling'' type models in which the current fluctuations are decoupled and the resistivity fluctuations are fundamental, and (2) drift'' type models in which the ambient current can be small (no resistivity fluctuations needed) and the current fluctuations are fundamental. In these turbulence frameworks, the important atomic physics based edge sources have been included (impurity radiation, ionization, and charge exchange effects).
