本文详细介绍了一台用于研究激光等离子体相互作用产生的电子束的单次激发电子谱仪。与传统的电子源相反，来自激光等离子体加速器的电子束可以产生宽范围的能量。因此，诊断这些电子光谱需要特别注意和实验发展。在这里，我们提供了一个绝对校准的Lanex柯达精细屏幕上的激光触发的射频皮秒电子加速器。电子束辐照屏的效率至今还没有被研究过。这种绝对校准，然后比较从一个积分电流Transformer的准单能电子光谱从激光等离子体相互作用的电荷测量。(c)2006年，美国物理学会。
This article gives a detailed description of a single shot electron spectrometer which was used to characterize electron beams produced by laser-plasma interaction. Contrary to conventional electron sources, electron beams from laser-plasma accelerators can produce a broad range of energies. Therefore, diagnosing these electron spectra requires specific attention and experimental development. Here, we provide an absolute calibration of the Lanex Kodak Fine screen on a laser-triggered radio frequency picosecond electron accelerator. The efficiency of scintillating screens irradiated by electron beams has never been investigated so far. This absolute calibration is then compared to charge measurements from an integrating current transformer for quasimonoenergetic electron spectra from laser-plasma interaction.
