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

这个泛欧洲项目将使用有史以来最大的线性质加，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，维德罗特设计的直线加需要一个不切实际的大型真空管。
