After the euphoria of last night was the euphoria of the morning debrief. Scientists here could scarcely believe their ears when they heard that the LHC had accelerated subatomic particles hundreds of thousands of times overnight in both directions. The particle accelerator has done more in a few short hours than it did in nine days last year before it broke down. The LHC's operating team believed that they may have the first low energy collisions by next week and higher energy's early next year.

经过昨晚的喜悦之后就是今晨汇报时的喜悦。科学家们简直难以相信自己的耳朵：一夜之间，加速器居然让两个方向的亚原子粒子的速度都增加了几十万倍！在去年碰撞机出故障以前，粒子加速器所用的时间是九天，而现在，所用的时间少了几个小时，但是产生的效果更好。LHC操作小组相信，他们到下周之前可以完成首次低能量碰撞，而明年年初则可以完成更高能量的碰撞。

Euphoria: an extremely strong feeling of happiness and excitement that usually lasts only a short time(通常指持续时间较短的)极度愉快的心情,极度兴奋的情绪

I was in a state of euphoria all day.
我整天都沉醉在极度兴奋之中.
