Thermo mechanical design of Collective Thomson Scattering components for ITER
France
The Collective Thomson Scattering (CTS) is a diagnostic system whose principal function is to diagnose the fast alpha particle population resulting from Deuterium-Tritium fusion reactions.
In the CTS diagnostic system, a high power probing beam (1 MW mm-wave at 60GHz) is scattered off from particles in the plasma. The spectrum of the scattered radiation (in the order of mW) yields information on such particles in the plasma.
F4E coordinated the design effort of several suppliers, where IDOM had to perform the design of the cooling lines for the system and assess the mechanical performance under the design loads. The design was assessed against the SDC-IC criteria of ITER.
