Title 367: JET/DIII-D similarity experiment on rotation in plasmas with low momentum input
Name:Filomena Nave mfn@ipfn.ist.utl.pt Affiliation:Instituto Superior Tecnico, Lisboa, Portugal
Research Area:Plasma Rotation Presentation time: Not requested
Co-Author(s): J. de Grassie ITPA Joint Experiment : Yes
Description: A JET/DIII-D similarity experiment on intrinsic rotation has been proposed for JET (at the moment accepted as a back-up experiment, expected to be executed in C32 depending on the availability of rotation measurements). If the JET experiment goes ahead, it will be necessary to produce plasmas with similar shapes at DIII-D for measurements of intrinsic rotation.
The main goal of this experiment is the determination of the size scaling for intrinsic rotation, which is crucial for extrapolation for ITER. The JET/DIII-D similarity experiment will complement existing and proposed DIII-D/C-Mod similarity experiments.
This experiment is part of the ITPA JEX TC-9.
ITER IO Urgent Research Task : No
Experimental Approach/Plan: JET intrinsic rotation experiments are planned to use a low triangularity configuration, low plasma currents (1-1.5 MA) and toroidal fields (1.1-1.7T) to achieve H-modes with high normalised beta values (1-2) using ICRH powers up to 4 MW. It is proposed to match JET shape and beta normalised values in DIII-D plasmas with ECH. Rotation should be measured during short NBI blips. We would like to compare JET and DIII-D intrinsic rotation during Ohmic and ECH phases.
