中能紧凑型X射线自由电子激光的可能性
On the Possibility of Medium-Energy Compact X-ray Free-Electron Laser
摘要：
研究了X射线自由电子激光在不规则微波荡器中的自放大自发发射问题。当自发辐射的频谱宽度的情况下，被认为是由源的空间分布产生的起伏场的条件。在这种情况下，受激辐射的增益函数比传统的波荡器高几十倍。本文提出了一种不规则微波荡器模型，它可用于构造一种廉价、紧凑的X射线自由电子激光。
英文摘要：
The problem of X-ray Free-Electron Laser operating on self-amplified spontaneous emission in irregular microundulator is considered. The case when the spectrum width of spontaneous radiation is conditioned by the spatial distribution of sources creating the undulating field is considered. In this case gain function of the stimulated radiation is dozens of times higher than that of the conventional undulators. We propose a model of irregular microundulator, which can be used to construct a drastically cheap and compact X-ray free-electron laser operating on medium energy electron bunch.
