用频闪Laser诊断一维离子束的有序性
Stroboscopic Laser Diagnostics for Detection of Ordering in One-Dimensional Ion beam
摘要:
提出了一种新的一维离子束有序化诊断方法。离子在沿光束的两个不同位置被脉冲激光激发,荧光由一组四个光电倍增管观察。荧光信号的相关性是离子束具有有序结构的可靠指示。
英文摘要:
A novel diagnostic method for detecting ordering in one-dimensional ion beams is presented. The ions are excited by a pulsed laser at two different positions along the beam and fluorescence is observed by a group of four photomultipliers. Correlation in fluorescence signals is firm indication that the ion beam has an ordered structure.
