中国环流器二号(HL-2A)是我国第一个具有偏滤器位形的核聚变实验装置,其放电水平和规模均上了一个新台阶。该实验装置长脉冲高参数放电运行需要数十粒氢(氘)弹丸连续注入,在偏滤器位形下进行改善约束和高密度运行的实验研究。根据HL-2A装置基本放电参数及实验需要,集合现有的技术水平,选择了一套原位冷凝30管气动发射系统[1]。
China Circulator No. 2 (HL-2A) is the first nuclear fusion experimental unit with divertor configuration in China. Its discharge level and scale have all reached a new level. The long pulse high parameter discharge operation of the experimental device requires dozens of continuous injection of hydrogen (deuterium) projectile, experimental study of improving the confinement and high density operation under divertor configuration. According to the basic discharge parameters and experimental needs of HL-2A unit, the existing technology level is collected and a set of 30-tube pneumatic launch system in situ is selected [1].
