The differences and similarities between the internal transport barriers (ITBs) of tokamak and
helical plasmas are reviewed. By comparing the characteristics of the ITBs in tokamak and …

An overview of the physics of intrinsic torque is presented, with special emphasis on the
phenomenology of intrinsic toroidal rotation in tokamaks, its theoretical understanding, and …

In this paper, recent progress on experimental analysis and theoretical models for non-local
transport (non-Fickian fluxes in real space) is reviewed. The non-locality in the heat and …

Poloidal and toroidal rotation has been recognized to play an important role in heat transport
and magnetohydrodynamic (MHD) stability in tokamaks and helical systems. It is well known …

The deuterium (D) operation was initiated in the LHD in 2017. In the first campaign of the D
experiments, we successfully extended the high temperature regime in the LHD. The new …

The ASDEX Upgrade intrinsic rotation database has been expanded to include a large
number of measurements from ohmic L-mode discharges covering a wide range of plasma …

Advanced momentum transport analysis is used to study matched hydrogen (H) and
deuterium (D) plasmas in the core of ASDEX Upgrade. The aim is to validate gyrokinetic …

A novel mechanism for driving residual stress in tokamak plasmas based on k∥ symmetry
breaking by the turbulence intensity gradient is proposed. The physics of this mechanism is …

Global gyrokinetic simulations have revealed an important nonlinear flow generation
process due to the residual stress produced by electrostatic turbulence of ion temperature …

Intrinsic rotation has been observed in I-mode plasmas from the C-Mod tokamak, and is
found to be similar to that in H mode, both in its edge origin and in the scaling with global …
