摘要

颗粒烧蚀机制是聚变等离子体中等离子燃料的一个有趣课题。在 GAMMA 10/PDX 中，计划进行用于产生更高密度等离子体的颗粒注入实验，以便在更高密度等离子体条件下进行分离等离子体实验。我们利用 GAMMA 10/PDX 的双向同步摄影系统测量了颗粒烧蚀云。在考虑等离子体中的颗粒轨迹和颗粒烧蚀时使用了层析成像重建技术。据我们所知，这是第一次清晰地获得等离子体中的三维颗粒轨迹和颗粒烧蚀图像。

Study of the pellet ablation cloud using the tomography technique for two-directional simultaneous photography in GAMMA 10/PDX

The pellet ablation mechanism is an interesting subject for plasma fuelling in fusion plasmas. In GAMMA 10/PDX, pellet injection experiments for higher density plasma production are planned to conduct detached plasma experiments in the higher density plasma condition. We measured the pellet ablation cloud by using the two-directional simultaneous photography system in GAMMA 10/PDX. The tomography reconstruction technique was used for considering the pellet trajectory in the plasma and pellet ablation. The three-dimensional pellet trajectory and pellet ablation images in the plasma were clearly obtained for the first time, to the best of our knowledge.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
