Study of momentum transport by transient analysis

Yoshida, Maiko

The momentum transport is one of the crucial parameter for determination of the rotation profile. Therefore, it is the critical importance to understand the properties of the momentum transport coefficients for the prediction of the rotation in next step devices. In some devices, many interesting results are reported using perturebative experiments. The purpose of this study is to understand the characteristics of momentum transport coefficients including diffusive and non-diffusive terms by multi-machine experiments over a wide range of magnetic configurations. A database of multi-machine analysis from plasma and engineering parameters scans will be constructed. We expand on existing data set with different values of non-dimensional parameters so as to establish a modeling/scaling and to predict rotation profile in ITER.
