The Divertor Tokamak Test (DTT) is a new facility designed by Italian DTT Limited Liability Consortium (S.C.ar.l.) [1] aimed at validating an integrated solution for the power exhaust in support of DEMO [2]. The ICRH system, part of the DTT complex of additional heating systems, in its final configuration shall couple to the plasma up to 6 MW in the 60–90 MHz frequency range. All the main radiofrequency passive components of the system have been designed and optimized with the Ansys High Frequency Structures Simulator (HFSS) computer code. In particular 3 dB hybrid couplers, stubs, stretchers and vacuum feedthroughs have been examined. Results of the optimization of these components are presented and discussed in this paper.
