Abstract

Abstract This paper presents the first comprehensive simulation study of p-11B fusion reactions in a spherical torus. We developed relevant program modules for fusion reactions based on energetic particle simulation frameworks and analyzed the two main fusion channels: thermal and beam-thermal. Using EHL-2 design parameters with n_boron=0.07n_ion and a hydrogen beam at 200 keV and 1MW, our simulation indicates that p-11B reactions produce approximately 1.5×10^15 α particles per second (~0.7 kW) from the thermal channel, and 5.3×10^14 (~0.25 kW) from the beam-thermal channel. We conducted parameter scans to establish a solid physics foundation for the high ion temperature conditions (T_i>26 keV) designed for EHL-2. This work also laid the groundwork for studying various operation modes to explore different reaction channels. The simulation results suggest that the conditions in EHL-2 could be sufficient for investigating p-11B thermonuclear reactions. In addition, we found that EHL-2 offers good confinement for energetic particles, allowing us to research the interactions between these ions and plasmas. This research enhances our understanding of burning plasma physics.
