我们利用日本大学电子束研究与应用实验室的s波段直线加速器，在太赫兹区域观测了强相干同步辐射（CSR）。测量了CSR功率的演变过程，并通过石英窗提取了弯曲磁体真空室中反射的CSR，提取时间为几十皮秒。自相关中延时CSR的长波包表明，延时CSR是弯曲磁体真空室的非共振衰响。为了设计一个高能加速器，必须减少康普顿后向散射产生的高能光子。
We observed intense coherent synchrotron radiation (CSR) in the terahertz region using an S-band linac at the Laboratory for Electron Beam Research and Application at Nihon University. The evolution of the CSR power was measured, and the CSR reflected in the vacuum chamber of the bending magnet could be extracted through the quartz window for a few tens of picoseconds. The long wave packet of the delayed CSR in the autocorrelation suggests that the delayed CSR was the non-resonant ring-down of the vacuum chamber of the bending magnet. To design a high-energy accelerator, it is necessary to decrease high-energy photons resulting from Compton backscattering with intense CSR.
