Spatiospectral conditioning of laser-plasma-accelerated electron beams using electromagnetic solenoids
Abstract
Microcoulomb-class electron beams from laser-plasma accelerators (LPAs) driven by kilojoule-class laser systems can enable high-flux electron radiography and copious secondary particle production. However, electron beam spatial properties such as transverse beam nonuniformity and large spatial scale at application sites can limit their utility. In this work, we demonstrate spatial conditioning of microcoulomb-class electron beams using electromagnetic solenoids as focusing optics. By applying ∼10 T solenoidal fields, we focused the electron beam onto a detection plane and measured a fluence enhancement factor of 6 over unconditioned electron beams. The chromatic focusing of the solenoids improved the resolution of electron beam radiographs produced using the focused electron beam. We also demonstrate a method using angled electromagnetic solenoids to simultaneously condition LPA electron beam spatial and spectral properties. These features are attractive for applications because they enable the spatial separation of a narrow-energy-spread population of the electron beam from the bulk of the electron beam.
