In the United States, thirty meters underground, a stone’s throw from Stanford University, scientists are fine-tuning the latest settings for the most powerful X-ray. It could revolutionize the way we study the building blocks of ‘Universe.
here is the Linac Coherent Light Source II, Where . It nestles thirty meters underground in the facilities of Slac, the particle accelerator laboratory located near Stanford University, in the United States. This is the most powerful . This type of beam is formed from a particle accelerator.
It is by going through a series ofthat he comes to produce the . The latter is capable of heating in less than a billionth of a second of to a million degree. One way to empty of their to examine them or to “film” the evolution of a interacting with another or even the structure of certain . It is a kind of atomic resolution microscope. Scientists can use these x-rays to create what they call molecular films.

1,000,000 pulses per second
Its predecessor, the LCLS, was already capable of producing X-ray pulses a thousand times brighter than anything else in the world.. With this version 2, the X-ray will be 10,000 times brighter than its predecessor. The laser is located in the 3 km long tunnel of the old linear from the center. While the LCLS peaked at 120 light pulses per second, this new version will manage to produce up to 1 million pulses per second, i.e. one pulse below one. .
Such a velocity dramatically increases the definition of what scientists can “see” and will allow access to experiments that were previously impossible to perform. The researchers had to revise the design of thefrom to be able to channel his release from . For this, they have integrated a series of modules maintained at -271 ° C. On this last day of the year, researchers are making the final adjustments to be able to test the LCLS-II by activating its first beam in January. The real x-ray is expected to be generated over the next summer.
