AI 中文摘要
近年来，激光等离子体加速器一直是广泛研究的主题。它们产生的电子束具有广泛的能量分布。为了方便地表征来自激光尾场加速（LWFA）的束流，通常使用与CCD相机耦合的闪烁屏的电子能谱仪。在这项工作中，我们校准了一系列DRZ荧光屏并测量了它们发出的光的光谱。校准是使用清华大学的射频线性电子加速器进行的，该加速器提供了峰值能量约为30 MeV的单能电子束。
英文摘要
Laser-plasma accelerators have been the subject of extensive research in recent years. The electron beams they generate exhibit a broad energy spread. To conveniently characterize beams from laser wakefield acceleration (LWFA), electron spectrometers employing scintillating screens coupled with CCD cameras are typically used. In this work, we calibrate a series of DRZ phosphor screens and measure the spectra of the light they emit. The calibration was performed using the radio-frequency linear electron accelerator at Tsinghua University, which provided monoenergetic electron beams with peak energy of approximately 30 MeV.
