ITER ECRH-ECCD System Capabilities for Extended Physics Applications

Physics fundamentals for ITER

The design of an experimental thermonuclear reactor requires both cutting-edge technology and physics predictions precise enough to carry forward the design. The past few years of worldwide physics studies have seen great progress in understanding, innovation and integration. We will discuss this progress and the remaining issues in several key physics areas. (1) Transport and plasma confinemen...

From profile to sawtooth control: developing feedback control using ECRH/ECCD systems on the TCV tokamak

Real time control of heating systems is essential to maximise plasma performance and avoid or neutralise instabilities under changing plasma conditions. Several feedback control algorithms have been developed on the TCV tokamak that use the electron cyclotron (ECRH/ECCD) system to control a wide range of plasma properties, including the plasma current, shape, profiles as well as the sawtooth in...

Health Physics Considerations for the ITER

Health physics aspects associated with operation of the ITER are investigated. ITER has health physics elements in common with existing facilities as well as unique features. Fusion facility neutron radiation is similar to that encountered in a low energy accelerator. The tritium hazard has radiation protection issues in common with the Canadian Deuterium reactor. Completion of the final ITER d...

Reflectometry Applications to Iter

Extended capabilities for visual cryptography

An extended visual cryptography scheme, EVCS for short, for an access structure (? Qual ; ? Forb) on a set of n participants, is a technique to encode n images in such a way that when we stack together the transparencies associated to participants in any set X 2 ? Qual we get the secret message with no trace of the original images, but any X 2 ? Forb has no information on the shared image. More...
