The goal of phase 2 is to achieve a continuous 2 Amp DC electron beam. This will be a significant accomplishment not only for
Free-electron Lasers, but may demonstrate technology useful in other areas such as
Illustration of the Phase 2 experiment
The Phase 2 beam optics configuration consists of a drift tube and quadrupole triplet to
symmetrically return the beam to the decelerator tube. The philosophy behind the Phase 2 experiment is to address the formidable
challenges to achieving DC beam operation without the complications imposed by the FEL.
