World's first X-ray Free Electon Laser (XFEL) is being built at SLAC (Stanford Linear Accelerator Center). This is so sweet, this has the potential to totally revolutionize crystallography.
The world's second XFEL might be built at DESY. I remember when I was over in Holland, they were talking about this quite a bit.
When I went to the IUCR in Florence, there was a great presentation about XFEL by a guy from SLAC, it blew me away.
