  • 英国自由电子激光加速器CLARA成功产生第一枚电子

    一阿秒(attosecond)是一秒的百亿亿分之一,一阿秒比一秒相当于一秒比320亿年。它也是英国科技设施研究理事会的达斯伯瑞实验室(DaresburyLaboratory)正在建造的自由电子激光加速器(FEL)所产生脉冲的时间。该加速器近期成功射出了第一枚自由电子,标志着由英国人设计建造的紧凑线性加速器CLARA可以正常工作,CLARA即将投入运行,为人类探索世界打开一个新的窗口。 自由电子激光加速器是当今世界加速器领域的研究重点,具有其它光源所无法比拟的优势,可广泛运用于物质结构探索、新能源发现、疾病防控等多个领域。但目前FEL技术尚处于起步阶段,有很大提升空间。原因是全球FEL装置很少,很多研究领
