在HL-2A托卡马克上，超声速分子束注入（SMBI）已发展成为常规的加注方式。系统的关键部件是电磁阀和锥形喷嘴。将阀和锥形喷嘴组装成用于产生脉冲光束的简化拉瓦尔喷嘴。该系统的附属设备包括用于冷却SMBI生成的冷却系统和用于定量注射的原位校准组件。与传统的充气方式相比，SMBI具有响应快、加注流量大的特点。这些优点使SMBI成为一种良好的加注方法、一种优秀的等离子体密度反馈控制工具和一种边缘局域模式缓解资源。
On HL-2A tokamak, supersonic molecular beam injection (SMBI) has been developed as a routine refueling method. The key components of the system are an electromagnetic valve and a conic nozzle. The valve and conic nozzle are assembled to compose the simplified Laval nozzle for generating the pulsed beam. The appurtenance of the system includes the cooling system serving the cooled SMBI generation and the in situ calibration component for quantitative injection. Compared with the conventional gas puffing, the SMBI features prompt response and larger fueling flux. These merits devote the SMBI a good fueling method, an excellent plasma density feedback control tool, and an edge localized mode mitigation resource.
