Abstract

This document contains the slides to a presentation held at US-JP Workshop on Theory Based Modelling. The presentation covered the following topics:

1. Dimensionless ITB temperature or pressure gradient characterizing ITB's on JET, (also used on Tore Supra, FTU, Alcator C-Mod;

2. Technique for controlling the current and pressure profiles in high performance tokamak plasmas with ITB's: a technique that offers the potential of retaining the distributed character of the plasma parameter profiles;

3. First experiments using the simplest lumped-parameter version of this technique for the current profile:
3.1. Control of the q-profile with one actuator: LHCD Modelling with CRONOS,
3.2. Control of the q-profile with three actuators: LHCD, NBI, ICRH Modelling with JETTO,

4. Ongoing experiments on simultaneous real-time control of the current density and temperature gradient profiles.
