我们报告了x射线跃迁辐射频谱的测量。用5 GeV和9 GeV的电子在多层聚丙烯箔的辐射体中产生X射线，用标定的单晶布拉格光谱仪在4 ~ 30 keV范围内检测X射线。实验结果与理论预测的光谱特征吻合较好。特别地，多箔辐射器明显的干涉图样和预期的辐射硬化随着箔厚度的增加被清楚地观察到。辐射的总强度比计算预测的要低一些。(AIP)
We report a measurement of the frequency spectrum of x-ray transition radiation. X rays were generated by electrons of 5 and 9 GeV in radiators of multiple polypropylene foils, and detected in the range 4 to 30 keV with a calibrated single-crystal Bragg spectrometer. The experimental results closely reproduce the features of the theoretically predicted spectrum. In particular, the pronounced interference pattern of multifoil radiators and the expected hardening of the radiation with increasing foil thickness are clearly observed. The overall intensity of the radiation is somewhat lower than predicted by calculations. (AIP)
