Description

The High Field Side Reflectometry is diagnostic equipment subjected to the conditions that are severe even for ITER: magnetic field over 9T, temperatures up to 700 ºC, strongly non-uniform temperature field, specific shape of the equipment with length of in-vessel waveguides about 10m and location of waveguides close to the blanket connectors where large halo currents are expected during disruptions make the development of reliable design challenging and make the role of multiphysics simulations extremely important. This study deals with eddy current, halo current, thermal and structural analyses of HFS Reflectometry. Specifics of the equipment leads to the necessity of performing electromagnetic analysis on the basis of global FE model of ITER sector including all in-vessel HFS Reflectometry components, which was developed and benchmarked against available at ITER database results. Modified approach to halo current analysis of HFS Reflectometry is proposed and discussed. Rational models for thermal and structural analyses as well as corresponding computational procedures are proposed and principal results of multiphysics simulations are presented and analyzed.
