Ｎew method to measure timing jitter of electron beam bunch micro-pulse

摘要: 提出了一种高灵敏度电子束微脉冲时间抖动的测量方法。该方法采用传统的测量束团位置及电荷量的四条带束流位置探头，用混合环对感应信号进行处理，对共振频率为2.856GHz的谐波分量用MIXER与2.856GHz的参考信号进行相位比较，并由此得到电子束团微脉冲时间抖动值。

Abstract: This paper presents a new method for measuring the timing jitter of micropulse with high sensitivity. Using the traditional four-stripline beam monitor which has been used to measure the electron beam position and electron charge, and by comparing the phase of the induced signals with the reference signal, the phase jitter, also the timing jitter are obtained.
