Development and Delivery of Final Design for ITER Core Plasma Thomson Scattering system (CPTS), Charge-eXchange Recombination Spectrometer (CXRS) and Parts of the Bolometer Diagnostic

The scope of this Framework Contract includes development and delivery of the final design up to build-to-print and manufacturing specifications for the following: - Core Plasma Thomson Scattering (CPTS) Diagnostic; - Charge-eXchange Recombination Spectrometer (CXRS) Diagnostic; and - Parts of the Bolometer Diagnostic. The CPTS will inject high power laser light into the ITER plasma via a series of mirrors and windows. Other mirrors will collect small amounts of light scattered from electrons in the plasma and focus the light onto an optical fiber bundle. The fibers will bring the light to a set of spectrometers. Analysis of the spectrum will provide information on the temperature and density of the plasma electrons. Laser light not scattered by the plasma electrons will be collected by a beam dump inside the ITER vessel. The CXRS will collect, via a series of mirrors, light emitted by charge-exchange processes as a beam of energetic neutral particles crosses the ITER plasma. As for the CPTS, lenses will focus the light onto an optical fiber bundle that will bring the light to a set of spectrometers. Analysis of the spectrum will provide information on ion temperature, rotation velocity and impurity concentrations in the plasma. The Bolometer Diagnostic will use a set of sensors distributed around the ITER plasma to provide information on the total radiated power in a wavelength range from infrared to soft X-ray. Bolometer cameras within the scope of this framework contract are metal structures with internal ceramic parts that house the sensors, collimate light from the plasma to provide spatially resolved information and provide electrical connections from the sensors to cabling.
