Fluid-cooled reflective x-ray source

During operation of the reflective target X-ray source, heat must be removed from many components. The electron beam must be diverted to the target and may interact with the structure along this path. Heat is also generated in the target itself. This may be excessive because only a very small percentage of the energy of the electron beam is converted into X-rays. Finally, the X-rays must exit the vacuum through a window, which can also be heated by the X-rays, reflected electrons and radiant heat from the target. A water-cooled reflective X-ray source provides water or other fluid cooling for the centering aperture, the X-ray target, and/or the exit window. 在反射靶X射线源的操作期间，必须从许多组件中移除热。电子束必须被转向至靶并且可沿此路径与结构相互作用。在靶本身中也产生热。这可能是过量的，因为只有非常小百分比的电子束的能量被转换成X射线。最后，X射线必须通过窗离开真空，窗也可由X射线、反射电子和来自靶的辐射热加热。水冷式反射X射线源为定心孔、X射线靶和/或出口窗提供水或其他流体冷却。
