CTS design 1


In February 2014, DTU (in a consortium with IST (Portugal)) entered into a four-year Framework Partnership Agreement (FPA) with Fusion for Energy (F4E) for the development of the Collective Thomson Scattering (CTS) diagnostic for ITER. The overall aim of the FPA is to develop, qualify, and provide the final design of in-vessel components of the CTS diagnostic to IO, as well as providing the functional specifications of the remaining parts of the diagnostic system in order for this to be designed and installed after the first plasma of ITER. These components include all ex-vessel components, high power gyrotron source, receiver electronics, and transmission lines.

Currently, the design teams at DTU and IST are developing the system design, developing performance analysis of the diagnostic, engineering and structural analysis etc. in preparation for the Intermediate Design Review in June 2017. The figure below shows some of the designed components.

During the years 2003-2007, the CTS group at DTU developed a conceptual and preliminary design for a CTS diagnostic system for ITER under contracts with EFDA. This work laid the foundation for the inclusion of a CTS diagnostic system in the ITER Baseline Design which was updated in 2007. The CTS diagnostic will have the primary objective to diagnose fast ion behavior across the plasma radius in ITER.
