Recent advances on ion cyclotron resonance heating scenarios for Divertor Tokamak Test facility

An analysis of the Ion Cyclotron Resonance Heating (ICRH) propagation and single-pass absorption in DTT (Divertor Tokamak Test facility) [1] heating scenarios has been performed by TOMCAT 1D full-wave kinetic wave equation code [2]. This analysis aimed to explore a wider parameter space compared to previous studies [3,4], with the goal of enhancing the understanding of DTT. Minority heating schemes at 3T and 6T were analyzed, simulating with different plasma species, including varying concentrations of D, 3He, and H, across the frequency range from 50 MHz to 90MHz. A very promising reduced-field configuration will be presented. Furthermore, three-ion heating schemes for full-field configurations were investigated, building on the findings from [5], leading to the identification of an efficient scenario. An analysis with TORIC [6] was subsequently carried out, providing positive feedback on the results obtained with TOMCAT.
