利用大阪大学的l波段直线加速器，采用磁束压缩方法，产生了26.5 MeV亚皮秒电子单束。在100 ~ 700 μm波长范围内观测到亚皮秒单束的相干跃迁辐射。强度比计算得到的非相干跃迁辐射高7.9×109times。根据跃迁辐射的光谱分析，估计压缩电子束的长度约为50 fs （rms）。相干跃迁辐射具有足够高的强度，可以作为脉冲光源应用于脉冲辐射分解。
Using a magnetic bunch compression method, a 26.5 MeV subpicosecond electron single bunch was generated with the L-band linac of Osaka University. The coherent transition radiation emitted from the subpicosecond single bunch was observed at wavelengths from 100 to 700 μm. The intensity was 7.9×109times higher than that of the incoherent transition radiation obtained by calculation. The length of the compressed electron bunch was evaluated to be roughly 50 fs (rms) from the analysis of the spectra of the transition radiation. The coherent transition radiation has high enough intensity to be applied to pulse radiolysis as a pulsed light source.
