SPARC is designed to be a high-field, medium-size tokamak aimed at achieving net energy gain with ion cyclotron range-of-frequencies (ICRF) as its primary auxiliary heating mechanism. Empirical predictions with conservative physics indicate that SPARC baseline plasmas would reach , which is well above its mission objective of . To build confidence that SPARC will be successful, physics-based integrated modelling has also been performed. The TRANSP code coupled with the theory-based trapped gyro-Landau fluid (TGLF) turbulence model and EPED predictions for pedestal stability find that is attainable in standard H-mode operation and confirms operation is feasible even with adverse assumptions. In this analysis, ion cyclotron waves are simulated with the full wave TORIC code and alpha heating is modelled with the Monte–Carlo fast ion NUBEAM module. Detailed analysis of expected turbulence regimes with linear and nonlinear CGYRO simulations is also presented, demonstrating that profile predictions with the TGLF reduced model are in reasonable agreement.

SPARC 托卡马克核心等离子体性能的预测

SPARC 被设计为一种高场、中型托卡马克,旨在以离子回旋加速器频率范围 (ICRF) 作为其主要辅助加热机制来实现净能量增益。保守物理学的经验预测表明,SPARC 基线等离子体将达到,远高于其任务目标。为了建立对 SPARC 成功的信心,还执行了基于物理的集成建模。TRANSP 代码与基于理论的困陀螺-朗道流体 (TGLF) 湍流模型和基座稳定性的 EPED 预测相结合,发现在标准 H 模式操作中可以实现,并确认即使存在不利假设,操作也是可行的。在此分析中,离子回旋波使用全波 TORIC 代码进行模拟,阿尔法加热使用 Monte-Carlo 快离子 NUBEAM 模块进行建模。
