At that time, we were working at the European Organization for Nuclear Research at the world's largest particle collider, which collides protons, by the way.

当时我们在欧洲核能研究所工作，那里有世界上最大型的粒子对撞器。

The new version of the machine will thus collide more protons, more often and at higher energies than previous incarnations.

因此，新版本的机器将碰撞更多的质子，比以前的版本更频繁且能量更高。
