橡树岭国家实验室 (ORNL) 开发的基于气动的氢同位素颗粒注射器已用于最近在欧洲联合环面 (JET) 上进行的等离子燃料实验。注射器由三个独立的机枪式机构组成（标称颗粒直径为 2.7、4.0 和 6.0 毫米），并具有准稳态条件（> 10 s）的重复操作（1-5 Hz）。一套广泛的注射器诊断功能可以评估每次丸粒射击的参数，包括速度、质量和完整性。颗粒速度范围为 1.0 至 1.5 km/s。 JET 的设备已发射了 3700 多个弹丸，其中约 1500 个弹丸用于等离子燃料实验。在最近的实验中，该系统性能非常出色，包括颗粒速度和质量的出色再现性，以及将颗粒输送到等离子体的可靠性 >98%。
A pneumatic‐based, hydrogen isotope pellet injector that was developed at the Oak Ridge National Laboratory (ORNL) has been used in recent plasma fueling experiments on the Joint European Torus (JET). The injector consists of three independent machine‐gun‐like mechanisms (nominal pellet sizes of 2.7, 4.0, and 6.0 mm in diameter) and features repetitive operation (1–5 Hz) for quasi‐steady‐state conditions (>10 s). An extensive set of injector diagnostics permits evaluation of parameters for each pellet shot, including speed, mass, and integrity. Pellet speeds range from 1.0 to 1.5 km/s. Over 3700 pellets have been fired with the equipment at JET, with about 1500 pellets shot for plasma fueling experiments. In recent experiments, the system performance has been outstanding, including excellent reproducibility in pellet speed and mass, and a reliability of >98% in delivery of pellets to the plasma.
