| 摘 要： | 考虑电子的相对论效应，根据电磁学理论和相对论公式建立了电子磁谱仪的原理；按照该原理设计了电子的磁谱仪，用补偿磁路改善了磁场的均匀性；按照磁谱仪的结构对其进行了测试和标定；以LiF热释光探测器作为记录元件，可获得相对论电子的能量分布。实验上典型的测量结果与国外计算机模拟的结果较好地一致，从而证明电子磁谱仪的可靠性。

| Abstract: | A principle of the relativistic electrons magnetic spectrometer has been established by the theory of electromagnetism and relativity. This spectrometer has been designed and improved on by using a compensatory magnet. The results of testing and scaling show that the magnetic field of spectrometer is uniform. An energy distribution of the relativistic electrons can be obtained by using a LiF thermoluminescent dosimeter (TLD). The experimental result from the spectrometer is better with that from 2D particle in cell (PIC) simulation, which reveals that the designed spectrometer is credible. |
