Power Balance in the ITER Plasma and Divertor

Divertor Requirements and Performance in ITER

Divertor interferometer diagnostic for ITER

In the harsh environment of the divertor region in ITER, plasmas spanning a huge density range from 1019 to 1022 m−3 are anticipated making measurement of the electron density particularly challenging. For any reasonable wavelength choice, the total phase measured by a conventional two-color interferometer system is always 2 and therefore subject to fringe counting errors. This problem can be r...

Status of the Engineering Design of the ITER Divertor

In this paper we present the main features of the ITER Divertor final dlesign from an engineering point of view and describe the present choices regarding layout, geometry and material selection. The assessment of the detailed design shows that the divertor is able to withstand the thermal and electromagnetic loading conditions foreseen for ITER, and that the estimated lifetime of the Plasma Fa...
