The pan-European project will generate intense neutron beams to study the structure of materials, using the most powerful linear proton accelerator ever built.

这个泛欧洲项用有史以来最强大的线性质子加速器，产强中子束研究材料的结构。

Lawrence realised that Viderot's design for a linear accelerator would require an impractically large vacuum tube.

劳伦斯意识到，德特设计的直线加速器需要一个不切实际的大型真空管。
