康普顿效应

In the DU FEL, an additional undulator with period close to the betatron wavelength in the main undulator is introduced to provide an additional mechanism of bunching.

我们建立起了包含了空间电荷效应的DU-FEL非线性理论，并在此基础上对高增益康普顿区及喇曼区DU FEL的增益及转换效率进行了解析分析和数值模拟研究。

First, the background spectrum is subtracted from experimental one; Second, by the spectrum stripping, the counts came from partial energy deposition of incidence photon in HPGe crystal, such as Compton scatting or pair production; the next, transform the experimental spectrum to the incidence photon flux spectrum.

实验数据的处理过程有三步：1 从实验谱中减掉本底谱；2 实验谱中分离掉各种能量的入射光子在晶体中的部分能量沉积(康普顿散射、电子对效应)：3 处理过的实验谱转成入射光子通量谱。比较结果显示，在本实验中，模拟谱对实验谱的总计数相对偏差不大于20%，两者基本符合。
