Predicting rotation for ITER via studies of intrinsic torque and momentum transport in DIII-D
Abstract
Experiments at the DIII-D tokamak have used dimensionless parameter scans to investigate the dependencies of intrinsic torque and momentum transport in order to inform a prediction of the rotation profile in ITER. Measurements of intrinsic torque profiles and momentum confinement time in dimensionless parameter scans of normalized gyroradius and collisionality are used to predict the amount of intrinsic rotation in the pedestal of ITER. Additional scans of Te=Ti and safety factor are used to determine the accuracy of momentum flux predictions of the quasi-linear gyrokinetic code TGLF. In these scans, applications of modulated torque are used to measure the incremental momentum diffusivity, and results show phenomenology consistent with the E B shear suppression of turbulent transport. These incremental transport measurements are also compared to TGLF results. In order to form a prediction of the rotation profile for ITER, the pedestal prediction is used as a boundary condition to a simulation that uses TGLF to determine the transport in the core of the plasma. The predicted rotation is 20 krad/s in the core, lower than in many current tokamak operating scenarios. TGLF predictions show this rotation is still significant enough to have a strong effect on con nement via E Bmore »
