[HTML][HTML] Control of quasi-monoenergetic electron beams from laser-plasma accelerators with adjustable shock density profile
The injection physics in a shock-induced density down-ramp injector was characterized,
demonstrating precise control of a laser-plasma accelerator (LPA). Using a jet-blade
assembly, experiments systematically varied the shock injector profile, including shock
angle, shock position, up-ramp width, and acceleration length. Our work demonstrates that
beam energy, energy spread, and pointing can be controlled by adjusting these parameters.
As a result, an electron beam that was highly tunable from 25 to 300 MeV with 8% energy …

Control of quasi-monoenergetic electron beams from laser-plasma accelerators
In this paper, we demonstrate a highly tunable, controlled-injection laser-plasma accelerator
(LPA) through systematically varying parameters of a density shock injector. Beam energy,
energy spread, charge and pointing can be controlled in the range of 50b300 MeV, with<
10% energy spread, 1.5 mrad divergence and< 1mrad pointing fluctuation. The beams are
repeatable, and suitable for high quality MeV Thomson photon sources or for injectors to
staged systems.
