1 kilometers make up the accelerator tunnel, where electron pulses are accelerated to prepare them for generating X-ray laser
The new atomic X-ray laser
fulfills a 1967 prediction that X-ray lasers
could be made in the same manner as many visible-light lasers -- by inducing electrons to fall from higher to lower energy levels within atoms, releasing a single color of light in the process.
But by the end of the eighties, Broad says, it had become obvious to everyone that the x-ray laser
would not work within the forseeable future.
In the current work, the researchers used the unprecedented x-ray intensity produced by the Linac Coherent Light Source x-ray laser
to observe the concerted nonlinear Compton scattering of two identical hard x-ray photons from the light element beryllium to produce a single higher-energy photon.
The X-ray laser
used in the new work is so much brighter and faster than its predecessors that researchers don't need to grow their molecule of interest into a big, sturdy crystal.
Its perhaps most important component, the nuclear-pumped X-ray laser
, is the center of a hitherto secret row among his own lieutenants.
The European X-Ray Free-Electron Laser Facility GmbH builds the European X-ray laser
on the company premises (BG) Bahrenfeld, Osdorfer Born and Schenefeld.
Department of Energy's (DOE) SLAC National Accelerator Laboratory scientists using SLAC's Linac Coherent Light Source (LCLS) X-ray laser
found that it takes only 1 trillionth of a second to flip the on-off electrical switch in samples of magnetite, which is thousands of times faster than in transistors now in use.
Like the hard X-ray laser
, the phonon laser--which doesn't produce electromagnetic waves at all--was a long time coming.
But as Roy Woodruff, associate director for defense systems at Lawrence Livermore National Laboratory, told Congress last year, "Certainly the scientifically significant breakthroughs in new weapon concepts, such as the X-ray laser
or any nuclear directed-energy weapon, would be stopped in the absence of testing.
Delivery of the terminals from Beckhoff PLC to control actuators in experiments at the European X-Ray Laser
(XFEL) in Hamburg.
