4月5日消息,据Engadget UK网站报道,如果你认为斯坦福大学使用超级明亮的X射线激光研究原子世界非常酷,那么你肯定会对它们的最新研发感兴趣。斯坦福和它的合作伙伴已经开始研究升级版的直线加速器相干光源II(LCLS-II),它的第二级激光束将比第一级明亮10000倍,速度快8000倍――大约为一百万脉冲每秒

4月5日消息,据Engadget UK网站报道,如果你认为斯坦福大学使用超级明亮的X射线激光研究原子世界非常酷,那么你肯定会对它们的最新研发感兴趣。斯坦福和它的合作伙伴已经开始研究升级版的直线加速器相干光源II(LCLS-II),它的第二级激光束将比第一级明亮10000倍,速度快8000倍――大约为一百万脉冲每秒。

斯坦福研发增强版X射线激光:亮度暴增1万倍

这一升级版激光将需要极端冷却(-456华氏度)、基于铌的超导体加速器谐振腔,后者可以实现几乎无损失的导电。相比之下,最初的激光以相对慢的速度,大约为每秒120脉冲,穿过室温的铜导体。

第一束X射线激光并不会消失,这两束激光的结合将覆盖更广的能量范围,帮助科学家们研究极其小、极其快的过程,在此之前这些过程都无法被记录,或者需要漫长的时间进行分析。最新的激光将导致促进电子学、能量和医学发展的新发现。最大的挑战就是等待这一设备的升级,这最早要等到2020年才可能实现。
