Abstract
Electrons from a source in a solenoidal magnetic field emerge from that field with a characteristic angular momentum. This behavior can be used to produce a flat ribbon-like electron beam with zero thickness (to first order). We show that this can be done using a quadrupole triplet and provide analytical expressions for the focal length of each lens. Solutions can be found over a wide range of practical values of the parameters.
