    Abstract

    Moving towards the era of burning fusion plasmas, a better knowledge of the physics of highly energetic particles, such as the 3.5 MeV fusion born alpha particles, becomes necessary. Diagnosing the fast ions in a fusion plasma is a challenging task, but the technique of collective Thomson scattering (CTS) provides the possibility of revealing the velocity distribution of the confined fast ions along a given direction – resolved both in time and space. Recently, the ITER baseline design has been expanded to include a fast ion CTS diagnostic. The design of this diagnostic was provided by the CTS group at Risø DTU building on the experiences and expertise gained from the group’s construction and current operation of the CTS diagnostic systems on the tokamaks TEXTOR and ASDEX Upgrade. This contribution will introduce the technique of CTS, give an overview of the current diagnostic systems and results, and present the expectations for the ITER CTS diagnostic.
