New test bed probes the origin of pulses at LCLS

It all comes down to one tiny spot on a diamond-cut, highly pure copper plate. That's where every X-ray laser pulse at SLAC's Linac Coherent Light Source gets its start. That tiny spot must be close to perfect or it can impair ...

X-ray laser pulses in two colors

(Phys.org) —SLAC researchers have demonstrated for the first time how to produce pairs of X-ray laser pulses in slightly different wavelengths, or colors, with finely adjustable intervals between them – a feat that will ...

Major milestone: First electrons accelerated in European XFEL

A crucial component of the European X-ray laser European XFEL has taken up operation: The so-called injector, the 45-metre long first part of the superconducting particle accelerator, has accelerated its first electrons to ...

Neutron production at ORNL's SNS reaches design power level

The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.

Small X-band photoinjector packs powerful punch

(Phys.org)—Accelerator physicists at SLAC have started commissioning the world's most compact photoinjector – a device that spits out electrons when hit by light. Photoinjectors are used to generate electrons for free-electron ...

Swift progress on NSLS-II booster

The electrons that will generate intense, focused beams of x-rays at NSLS-II are accelerated to their target energy before they enter the large main ring. That crucial job falls on a complex of equipment known as the injector, ...

Modern modulators for Fermilab accelerators

Take a walk along the hall that houses Fermilab's linear accelerator, and you'll see tall sets of brightly lit shelves that resemble fancy vending machines. But instead of snacks and beverages, they hold boxy structures that ...
