Abstract: A composite target is provided and is interacted with an electron to generate an X-ray, and an energy of the electron can be changed by controlling a tube voltage at least. The composite target includes a target body and an interposing layer which is connected with the target body. The interposing layer moves a highest peak of an energy spectrum of the X-ray toward a high energy direction. The interposing layer may be a single metal or a metal mixture. Not only a low energy photon of the X-ray can be filtered by the interposing layer, but also a distribution of the low energy photon of the X-ray can be increased by increasing a thickness of the interposing layer. As the tube voltage is enhanced, an amount of a high energy photon of the X-ray generated is dramatically increased. An X-ray tube containing the above composite target is also provided.

Abstract translation: 提供复合靶并且与电子相互作用以产生X射线，并且可以通过至少控制管电压来改变电子的能量。 复合目标包括与目标体连接的目标体和中介层。 插入层将X射线的能谱的最高峰向高能方向移动。 中间层可以是单一金属或金属混合物。 X射线的低能量光子不仅可以通过中介层进行滤光，而且可以通过增加中间层的厚度来增加X射线的低能量光子的分布。 随着管电压的增加，所产生的X射线的高能量光子的量显着增加。 还提供了含有上述复合靶的X射线管。
