Overview of Enhanced D-alpha and Quasi Continuous Exhaust H-modes at DIII-D
N. Leuthold, Z. Li, M. Faitsch +19
We review the Enhanced D-alpha (EDA) and Quasi-continuous Exhaust (QCE) H-modes that have recently been achieved in the DIII-D tokamak. These scenarios are free of large type-I edg…

Conceptual study on using Doppler backscattering to measure magnetic pitch angle in tokamak plasmas
AK Yeoh, VH Hall-Chen, QT Pratt +8
We introduce a new approach to measure the magnetic pitch angle profile in tokamak plasmas with Doppler backscattering (DBS), a technique traditionally used for measuring flows and…
