    Abstract

    The EFDA Contract 04-1213 with Risø National Laboratory concerning a detailed integrated design of a Fast Ion Collective Thomson Scattering (CTS) diagnostic for ITER was signed on 31 December 2004.
    In 2003 the Risø CTS group finished a feasibility study and a conceptual design of an ITER Fast Ion Collective Thomson Scattering System (Contract 01.654) [1, 2]. The purpose of the CTS diagnostic is to measure the distribution function of fast ions in the plasma. The feasibility study demonstrated that the only system that can fully meet the ITER measurement requirements for confined fusion alphas is a 60 GHz system. The study showed that with two powerful microwave sources of this frequency (gyrotron) and two antenna systems, one on the low field side (LFS) and one on the high field side (HFS), it should be possible to resolve the distribution function of fast ions both for perpendicular and parallel velocities with good spatial and temporal resolution.
    The present report, which is a continuation of this work, presents a detailed CATIA design of the two antennae systems, modified and extended calculations on beam overlap and scattering, measurements and calculations of the beam transmission through the blanket gap, and calculations of diagnosing fuel ion ratio and rotation velocity by CTS.
