Conceptual Design ICRH Antenna Support Structure

The text describes an "innovative" support for the ICRH antenna for the DTT, redesigned to respect space constraints, support 40 tons, and limit displacement to less than 1 mm.The original tubular structure was too deformable (2 mm). After several attempts with IPE and HEA/HEB sections, the optimal solution was identified in HEB 120 beams.The final version, completely bolted to improve maintenance, was verified with FEM analysis: the maximum displacement is 0.69 mm and the stresses are within the limits.The structure thus satisfies all requirements and is ready for integration into the DTT system.
