Abstract
A method for aligning the axis of an atom beam with the orientation of an electric field at a particular location within an enclosure for use in creating a charged particle source by photoionizing a cold atom beam. The method includes providing an atom beam in the enclosure, providing a plurality of electrically conductive devices in said enclosure, evacuating the enclosure to a pressure below about 10millibar, and aligning the axis of the atom beam with the orientation of the electric field, relative to each other, within less than about two degrees. Alignment may be facilitated by applying at least one voltage to the electrically conductive devices, mechanically tilting the atom beam's axis orientation of the electric field relative to each other and/or causing a deflection of the atom beam.
