Imaging in the water window has traditionally relied on large synchrotron radiation sources. Now, a tabletop tunable X-ray source which generates water-window X-ray photons from a low energy electron beam interacting with a van der Waals crystal has been demonstrated.

小调谐 X 射线源可能产生较大影响


传统上，水窗中的成像依赖于大型同步辐射源。现在，已经展示了一种台式可调谐 X 射线源，它从与范德华晶体相互作用的低能电子束中产生水窗 X 射线光子。
