The study discussed the preliminary mechanical design of a fast-ion loss detector for the JT-60SA tokamak, estimated probe head motion through numerical simulations, and presented finite element thermal assessment as well as preliminary electromagnetic analysis to evaluate potential disruptions on the system's structural components.
A fast-ion loss detector (FILD) is being designed for the JT-60SA tokamak. In this work, the preliminary mechanical design of this diagnostic is described. The expected motion needed to move the probe head between the parking and the measuring positions has been estimated by numerical simulations. A finite element thermal assessment of the detector is presented, to characterize its thermal response during the operation of the machine. Finally, the results of a preliminary electromagnetic analysis are reported to evaluate the impact of major disruptions on the structural components the system.
