超声分子束注入作为一种新的托卡马克加料方法 ,已成功地开发和应用于环流器新一号 (HL 1M)和超导托卡马克HT 7.近期开展的高气压超声分子束注入实验 ,在束流中发现了团簇流 ,其注入等离子体深度超过 17cm .电子密度上升率接近于小型冰弹丸加料 .多脉冲超声分子束注入形成电子密度阶梯形上升 ,类似于多弹丸加料效果 ,电子温度剖面呈中空分布 .描述了在HL 1M装置同一次欧姆放电等离子体中超声分子束与冰弹丸加料效果的实验比较 . As a new tokamak feeding method, ultrasonic molecular beam injection has been successfully developed and applied to the new HL1 and superconducting Tokamak HT7. Recently, the experiment of high pressure ultrasonic molecular beam injection , Cluster flow was found in the beam and the plasma injection depth was more than 17 cm.The rate of electron density rise was close to that of the small ice projectile.The injection of multi-pulse ultrasound molecular beam formed a ladder-like electron density rise similar to the effect of multi- The electron temperature profile is hollow, and an experimental comparison of the effect of the ultrasonic molecular beam and ice projectile on the HLM device with the same ohmic discharge plasma is described.
