Title: Magnetized and Flat Beam Generation at the Fermilab's FAST Facility

Abstract

Canonical-angular-momentum (CAM) dominated beams can be formed in photoinjectors by applying an axial magnetic field on the photocathode surface. Such a beam possess asymmetric eigenemittances and is characterized by the measure of its magnetization. CAM removal with a set of skew-quadrupole magnets maps the beam eigenemittances to the conventional emittances along each transverse degree of freedom, thereby yielding a flat beam with asymmetric transverse emittance. In this paper, we report on the ex- perimental generation of CAM dominated beam and their subsequent transformation into flat beams at the Fermilab Accelerator Science and Technology (FAST) facility 1. Our results are compared with numerical simulations and possible applications of the produced beams are discussed.
