渡越辐射及其在北京自由电子激光装置束测中的应用

The intensity of transition radiation decreases with the increase of target thickness.

光发射光强随靶厚度的增加而减小。

Finally, the long wavelength radiation from the wiggler is compared with the undulator transition radiation and the bending magnetic edge emission. The result shows that long wavelength radiation from the wiggler is the strongest one.

比较了弯转磁铁的边沿辐射、波荡器的渡越辐射和wiggler长波辐射，表明wiggler在红外波长范围辐射的性能最优。

The calculated threshold temperature is found to be in good agreement with the experimental laser-starting temperature, which indicates the resonance radiation trapping is a significant factor in establishing the population inversion of the resonance to metastable transition lasers.

发现计算得到的阈值温度与实验报道的开始产生激光的工作温度一致，表明共振辐射俘获效应是这类激光形成粒子数反转的一个重要机制。

This paper reports hot electron energy spectrum measured with electron spectrometer, and Optical Transition Radiation measured with optical time-integrated image of CCD during the interaction of laser-solid target in targets at the rear-side radiation of laser on 20 Terawatt femtosecond laser facility.

报道了在20TWfs激光器上采用电子磁谱仪和光学CCD积分成像相机分别对激光固体靶相互作用在靶背方向产生的超热电子能谱及其光学渡越辐射进行的测量。

In Chapter two, considering the energy equation, we study this mechanism, and find that a thermal instability of a radiation pressure-supported SSD can trigger such a transition.

在第二章，我们考虑了能量方程，研究了SSD内区的不稳定引发SSD-ADAF的转变机制，结果表明辐射压主导的SSD内区的热不稳定性能够触发这样的转变；
