摘要

Accelerator physicists have a vision: an energy-efficient X-ray source that can make high-resolution movies of molecules in chemical reactions. And the US National Science Foundation (NSF) has backed the dream - since 2005, it has invested more than US$50 million to develop such a source, most likely beneath the campus of Cornell University in Ithaca, New York. But there is one big problem: despite the inflow of cash, no US government agency has any plans to build the machine.
