On Friday scientists sent the first beam of particles around the machine - but without attempting any collisions.

上周五科学家试验性的第一次发射了粒子光束 -- 但没有尝试任何的粒子碰撞。

TEMs work by firing a beam of electrons through the material and measuring how it absorbs and deflects the particles to build up an image of the sample.

TEMs 的工作原理是通过发射一束电子穿过某种物质，并测量它如何吸收和偏转粒子来建立样本的图像。

But a powerful beam of subatomic particles could be used to crush nuclei together strongly enough so they fuse.

而强大的亚原子粒子束可以用来粉碎原子核，其强烈程度足以使它们融合。

Pier Oddone, Fermilab's boss, plans to follow it with the Long Baseline Neutrino Experiment (LBNE), which will send a yet-more intense beam of the particles to an underground laboratory in South Dakota.

This fireball, which lasts just 10 million, billion, billionths of a second, can be detected because it absorbs jets of particles produced by the beam collisions.

The tractor beam is very selective in the properties of the particles it acts on, so you could pick up specific particles in a mixture.
