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
