Description

The SPARC tokamak, under construction in Devens, Massachusetts, USA, plans to begin operation in 2026 and is predicted to produce over 100 MW of DT fusion power in a high power H-mode [Creely JPP 2020]. The results from this device will inform the design of ARC, a fusion power plant which aims to begin operation in the early 2030s. This work will show simulation results from the Monte Carlo code ASCOT5 of the orbits of fusion-born alpha particles in both SPARC and ARC. Detailed simulations of alpha losses to the planned wall geometry of SPARC building on previous work [Scott JPP 2020, Braun PPCF 2022] will serve as predictions for the operation of this device, informing interpretation and data analysis of diagnostic results, while initial toroidal ripple loss simulations for a proposed ARC design will allow for comparison to SPARC, ITER, and other future fusion devices.
