Beam Dynamics for the Scopius Conceptual Design Report
@article{Ekdahl2017BeamDF, title={Beam Dynamics for the Scopius Conceptual Design Report}, author={Carl August Jr. Ekdahl}, journal={arXiv: Accelerator Physics}, year={2017} }
Scorpius is a new multi-pulse linear induction accelerator (LIA). It is presently planned for Scorpius to accelerate four 2-kA electron pulses to 20 MeV from an injected energy of 2 MeV. The goal of Scorpius is to deliver a multi-pulse electron beam with quality sufficient for use in flash radiography of large-scale explosively-driven experiments. Beam physics has a profound effect on the quality of multi-pulse radiographs. Beam halo or asymmetry causes emittance growth, which enlarges spot…
