Abstract

To facilitate experimental management, feedback, and provide a platform for artificial intelligence (AI) model, a digital twin (DT) system has been developed for the negative ion based neutral beam injection (NNBI) at the comprehensive research facility for fusion technology (CRAFT). This system is capable of simulating experimental operations in a virtual space, mapping the operational status of the radio frequency based negative ion source (RF-NIS) of NNBI, and providing real-time feedback on experimental outcomes. This paper details the design and implementation of the CRAFT NNBI DT system. On the physical side, the system replicates complex entity system and simulates the actual workflow of the NNBI. On the DT side, it involves the dynamic state mapping of NNBI entity and the interaction exchange of real and virtual data. The system enables enhanced control over NNBI operations and experimental feedback, thereby supporting the implementation of future kilosecond long-pulse experiments.

为了方便实验管理和反馈，并为人工智能（AI）模型提供一个平台，我们为聚变技术综合研究设施（CRAFT）的负离子中性束注入（NNBI）开发了一个数字孪生（DT）系统。该系统能够在虚拟空间中模拟实验操作，映射 NNBI 的射频负离子源（RF-NIS）的运行状态，并提供实验结果的实时反馈。本文详细介绍了 CRAFT NNBI DT 系统的设计和实施。在物理方面，该系统复制了复杂的实体系统，模拟了 NNBI 的实际工作流程。在 DT 方面，它涉及 NNBI 实体的动态状态映射和真实与虚拟数据的交互交换。该系统可加强对 NNBI 运行和实验反馈的控制，从而支持未来千秒长脉冲实验的实施。
