We proposed and demonstrated a novel technique to measure time-resolved transverse emittances of the hydrogen ion (H) beam in a 1-GeV high-power accelerator. The measurement is performed in a nonintrusive manner by using a laser comb—laser pulses with controllable multilayer temporal structure. The technique has been applied to the transverse emittance measurement of a 1-GeV H beam in the Spallation Neutron Source high energy beam transport line. More than 20 time-resolved emittances have been simultaneously determined within a macropulse, a single minipulse, or a single bunch of the 1.4-MW neutron production H beam from a single measurement.

使用激光梳非侵入式测量1-GeV工作氢离子束的时间分辨发射率

我们提出并演示了一种测量氢离子时间分辨横向发射率的新技术(H-)在1-GeV大功率加速器中发射光束。通过使用具有可控的多层时间结构的激光梳-激光脉冲,以非介入方式执行测量。该技术已应用于1-GeV的横向发射率测量H-中子源高能束传输线中的电子束。在一个大脉冲,一个小脉冲或一堆1.4兆瓦中子产量中,同时测定了20多个时间分辨的发射率H- 一次测量的光束。
