Researchers Make Key Gains in Unlocking the Promise of Compact X-ray Free-Electron Lasers

Jeroen van Tilborg, Sam Barber, and Carl Schroeder lean over the chicane magnets that connect the laser plasma accelerator (behind them) to the downstream undulator. The electron beam excursion in the chicane allows for remnant laser light to be blocked, while also temporally separating electrons of different energies to reduce the sliced energy spread.

Tapering In Gas Jets Increases The Efficiency Of 10-GeV Class Laser Plasma Accelerators

(a) Gas jet density measurement setup. The phase offset of the probe beam (∼3 cm diameter) after it passes through the gas plume was measured using a wavefront sensor. (b) Example microscope image of gas jet throat used for width measurements. (c) Raw phase data measured from a representative shot. A 3D model of a small section of the 30 cm elliptical gas jet is shown in (d). Image courtesy of the ATAP Division
