Connecting the global H-mode power threshold to the local radial electric field at ASDEX Upgrade

The relation between the macroscopic input power required at ASDEX Upgrade to access the H-mode Pthr and the microscopic E×B shear has been investigated via fast charge-exchange recombination spectroscopy (CXRS) measurements at various toroidal magnetic fields, different electron densities, and in b...
