报告人简介：

Dr. Simone Carusotti is a 27 years old Post-doc and Mechanical Engineer at the University of Tuscia (UNITUS) in Italy, specializing in the design and development of tokamak engineering systems for fusion energy research. He earned his Ph.D. in Engineering for Energy and Environment in February 2025, with Doctor Europaeus distinction, focusing on the TRUST project. Dr. Carusotti has conducted extensive work on electromagnetic and structural modeling of fusion components, including collaborations with Tokamak Energy Ltd, CFS and contributions to EUROfusion’s WPDES programs. As leader of the TRUST project and design, he has worked also in HTS coil design, magnetic diagnostics, and experimental infrastructure for tokamaks. In addition to his research, he is actively involved in teaching and thesis supervision in nuclear fusion technologies at UNITUS.

报告摘要：

The main aim of this study is to explore a conceptual Alternative Magnetic Layout (AML) for the future nuclear fusion reactor based on the Tokamak concept. The proposed concept is eventually applied as a large down-scaled study for the new academic tokamak Tuscia Research University Small Tokamak (TRUST), under construction at University of Tuscia (UNITUS). In this proposal the Central Solenoid (CS) is placed around the Toroidal Field (TF) coils providing a relevant reduction in the reactor size. In order to compensate for the increase of the toroidal field on the coils, which is intrinsic in such a proposal, High Temperature Superconductor (HTS) material is foreseen for the TF coils. An overview of the proposed design and a possible plasma scenario is presented showing the AML advantages and disadvantages. The electromagnetic and structural characterizations for a preliminary design of the TF coils system is included in this paper to prove the engineering feasibility of the solution. Moreover, the involvement of the AML design in the TRUST project framework is presented. TRUST is a flexible and low-cost university-class experiment, to train the next generation of fusion engineers and physicists. Beyond its academic goal, TRUST is designed to allow easy replacement of the plasma facing components and testing innovative technologies (i.e., meta-materials) and materials including a feasible upgrade of the magnetic system from copper to HTS.
