Abstract

837,140. Ion sources. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 16, 1958 [Oct. 11, 1957], No. 31903/57. Class 39(1). A mass spectrometer ion source, suitable for use with gaseous samples such as uranium hexafluoride, includes an electrode 5 having a base or two similar and parallel upstanding walls defining a path for an ionizing electron beam 12, each wall having therein a series of apertures occupying the major part of the surface area of the wall, so that the electrode has a small surface area whilst providing for a uniform electric field along the path of the ionizing electron beam where it traverses a molecular flow beam of the sample to be ionized. The reduced surface area of the electrode 5 together with concentration achieved using molecular beam flow, limits the amount of adherence by traces of the sample on the walls of the source and thus the memory effect is reduced and the life of the ion source is increased. The sample to be ionized enters the source through an aperture 6 having a diameter equal to or less than its length, from a tube of the same diameter, to promote molecular beam flow.
