Design and optimization of a compact laser-driven proton beamline [PDF]

open access: yes, 2018
Laser-accelerated protons, generated by irradiating a solid target with a short, energetic laser pulse at high intensity (I > 1018W·cm-2), represent a complementary if not outperforming source compared to conventional accelerators, due to their intrinsic

Plasma Lens Backgrounds at a Future Linear Collider [PDF]

open access: yes, 2002
A 'plasma lens' might be used to enhance the luminosity of future linear colliders. However, its utility for this purpose depends largely on the potential backgrounds that may be induced by the insertion of such a device in the interaction region of the ...
