摘要:

相对论性电子束团具有大能量色散的能谱是用常规磁谱仪很难获得的。基于对探测激光脉冲以任意入射角入射到电子束团时汤姆逊散射产生的光子的分析,提出了一种新的光谱概念。研究了用能量校准CCD器件作为探测器的单脉冲光谱仪的可行性。在典型的实际实验条件下进行的数值模拟表明了新方法的有效性和准确性。

英文摘要:

The spectrum of relativistic electron bunches with large energy dispersion is hardly obtainable with conventional magnetic spectrometers. We present a novel spectroscopic concept, based on the analysis of the photons generated by Thomson Scattering of a probe laser pulse inpinging with arbitrary incidence angle onto the electron bunch. The feasibility of a single-pulse spectrometer, using an energy-calibrated CCD device as detector, is investigated. Numerical simulations performed in conditions typical of a real experiment show the effectiveness and accuracy of the new method.
