论文摘要
本文描述了KEV Energy电子的新射频计时器。它基于通过500 MHz射频场通过500 MHz射频场进行圆周或椭圆形的kev电子扫描。通过将入射电子的时间分布转换为圆或椭圆形上的命中位置分布，该设备实现了非常精确的时机。条纹摄像机基于类似的原理，通常在PS和SUB-PS时域运行，但与读数系统相关的大量停留时间。在这里，我们报告了一种新型的RF时正时技术，其中由微通道板和延迟线阳极组成的位置传感器产生的持续时间脉冲量很小。用子PS持续时间激光脉冲制成的测量值与射频功率同步，产生的时间分辨率约为10 ps。这种超高的精度技术在多种科学设备中具有潜在的应用，在所有情况下，电子都会定时并在同一设备中同时检测到。
This paper describes a new radio frequency timer of keV energy electrons. It is based on a helical deflector, which performs circular or elliptical sweeps of keV electrons, by means of 500 MHz radio frequency field. By converting a time distribution of incident electrons to a hit position distribution on a circle or ellipse, this device achieves extremely precise timing. Streak Cameras, based on similar principles, routinely operate in the ps and sub-ps time domain, but have substantial dead time associated with the readout system. Here, we report a new type of RF timing technique, where the position sensor, consisting of microchannel plates and a delay-line anode, produces ~ns duration pulses with small dead time. Measurements made with sub-ps duration laser pulses, synchronized to the radio frequency power, produced a timing resolution of ~10 ps. This ultra-high precision technique has potential applications in a large variety of scientific devices, and in all cases, electrons are timed and detected simultaneously in the same device.
