Abstract

816,681. Ion sources. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Jan. 6, 1956 [Jan. 7, 1955], No. 556/56. Class 39(1). An ion source comprises a chamber 1 connected to a pump 5, a nozzle 2 for introducing a jet of gas 3 into the chamber at high speed, preferably a supersonic speed, an H.F. coil 9 for ionising the gas molecules and an electric or magnetic field 14 for deflecting the ions so as to pass through the opening 10. A stream of electrons may be fired across the gas jet to ionise the gas molecules instead of using the coil 9, and the electrons may be caused to oscillate by reflection. Shock waves are formed in the gas jet and the ionising coil, or electron stream is located at a nodal point 8. The end wall 6 of the chamber has a cooling jacket 18. The ion source is preferably used in an isotope separator.
