Abstract

723,861. Heavy-ion-beam tubes. SKINNER, H. W. B. Nov. 25, 1948 [Nov. 25, 1947], No. 30657/48. Class 39 (1). An arrangement for concentrating a beam of charged particles consists of electrodes arranged in parallel planes, each plane containing a number of curved electrodes which engage one within the other. A beam from the projector 12, Fig. 1, is deflected by a transverse magnetic field so that those having different mass e.g. U235 and U238, are focused onto different parts of the collector 13. Concentration is produced by four parallel sets of nested electrodes 18a, 18b, 18c and a central electrode 19 fixed to the wall 11c of the tank by insulators 16 and a frame 15. The electrodes are connected together by rods 17 and the potentials may increase or decrease outwardly. Cups fitted to the electrodes hold the ends of the insulators.
