Abstract

In the near future the interior materials of JET will be changed to a beryllium wall and tungsten divertor so as to resemble the ITER design. Initially there will be no carbon strike plates in the divertor but there is the possibility of adding these later for an exact match. Such a change requires upgraded spectroscopic diagnostics in order to measure the spatially dependent influx of these impurities and their concentrations in the confined plasma. With 74 ionization stages (many of them very complex) the high Z of tungsten also places new demands on the atomic physics required to model its behavior which in turn informs the design of potential diagnostic systems. Modeled emission patterns from the upgraded JET are used as part of the diagnostic specification. We describe a suite of spectroscopic diagnostics in the visible, extreme ultraviolet, vacuum ultraviolet, and x-ray spectral regions suitable for these tasks. (c) 2006 American Institute of Physics.
