Germany Unveils World's Most Powerful X-Ray Laser (theguardian.com)
An anonymous reader quotes a report from The Guardian: The world's most powerful X-ray laser has begun operating at a facility where scientists will attempt to recreate the conditions deep inside the sun and produce film-like sequences of viruses and cells. The machine, called the European X-ray Free Electron Laser (XFEL), acts as a high-speed camera that can capture images of individual atoms in a few millionths of a billionth of a second. Unlike a conventional camera, though, everything imaged by the X-ray laser is obliterated -- its beam is 100 times more intense than if all the sunlight hitting the Earth's surface were focused onto a single thumbnail. The facility near Hamburg, housed in a series of tunnels up to 38 meters underground, will allow scientists to explore the architecture of viruses and cells, create jittery films of chemical reactions as they unfold and replicate conditions deep within stars and planets.
XFEL is the world's third major X-ray laser facility -- projects in Japan and the U.S. have already spawned major advances in structural biology and materials science. The European beam is more powerful, but most significantly has a far higher pulse rate than either of its predecessors. "They can send 100 pulses out per second, we can send 27,000," said Robert Feidenhan'l, chairman of the European XFEL management board. This matters because to study chemical reactions or biological processes, the X-ray strobe is used to capture flickering snapshots of the same system at different time-points that can be stitched together into a film sequence.

I'm assuming for biological and chemical processes it's used similar to femtosecond laser video photography where completely different trials are filmed at ever so slightly different times and angles on the same setup so as to create the illusion of a time sequence of a single event over a sizable area.

I came here to ask, who comes up with a simile like that?
It's MASER (Microwave Amplification Stimulated by Emissions of Radiation) and not LASER.

The X-ray pulse is so short that you get an image before the sample flies apart
but the shark must be huge!
Not as silly as it sounds. When the SLAC LCLS laser first operated the thing that convinced us we had roughly the power we thought was that it burned a hole in a metal foil. Actually finding something to serve as an X-ray beam stopper is not so easy at these powers.
...rright away vith his powerrful new x-rray machine.

No it is a European thing located in Germany. However, the tunnels where financed and built by the German government, the lab is a German company (by law) and it is related to DESY.
It is 3.4 km long (2 guaddle fotts 7 notches) hard to make that really small to be able to put it on a train. Men in Black gun is still out of reach.
