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

Year: 2026

Type: article

Abstract: An analysis of Ion Cyclotron Resonance Heating propagation and single-pass absorption in Divertor Tokamak Test facility (DTT) heating scenarios has been performed using the 1D full-wave code TOMCAT. This study aimed to explore a broader parameter space compared to previous works, with the goal of improving the understanding of DTT heating performance. Heating schemes at 3T and 6T were analyzed, simulating different plasma compositions with varying concentrations of D, 3He, and H, across a frequency range from 50 to 90 MHz. A very promising reduced-field configuration is presented. Furthermore, three-ion heating schemes for the full-field configuration were investigated, leading to the identification of an efficient scenario. Additional analyses with TORIC and EVE were carried out, providing positive validation of the results obtained with TOMCAT.
