高能电子束的电光探测方法

Energetic Electron Bunch Measurement Based on Two Electro-optic Detection Techniques

本文介绍两种电光探测方法测量电子束长度 :延迟扫描法、啁啾脉冲法 (包括啁啾脉冲光谱仪法和啁啾脉冲互相关法 ) ,并比较了不同方法的速度、时间分辨率 .论文还讨论了使用电光晶体时吸收和色散对电子束电场形状的影响 。

Two electro\|optic detection techniques-delay\|scan method and chirped\|pulse methods are described,which are used to measure an electron bunch length.Temporal resolution and measurement speed of different methods are compared.We also discussed that absorption and dispersion of the electric field and probe laser in the crystal led to a distortion of the measured electric field profile.Issues related to the synchronization between the electron bunch and the probe laser pulse will be discussed.
