Abstract

1,085,485. Electrostatic generators; rectifying. UNITED STATES ATOMIC ENERGY COMMISSION. March 21, 1966 [April 6, 1965], No. 12249/66. Headings H2A and H2F. A method of producing a beam of alternatelycharged groups of liquid metal droplets comprises: forming liquid metal into droplets, inducing charge in the droplets as they are formed (the polarity of the induced charge reversing periodically), and accelerating groups of the droplets through an alternating travelling electric field, this field having the same period as the period of reversal of charge in the droplets. Preferably the groups are collected, according to charge, in two separate collectors, whereby a very high D.C. voltage is generated; from another aspect, the A.C. which induces charges in the droplets is thus rectified. As shown, liquid alloy from a container 30 is fed to a nozzle 18 vibrated ultrasonically at 33 to produce uniform-diameter droplets; the nozzle is earthed and opens into an evacuated bell-jar 39. A charge is induced in the droplets by a toroidal electrode 8 secured to a supporting rod 14. Further toroidal electrodes 9 to 11 are provided, and all are secured alternately to supporting rods 14, 15, connected to the output terminals 24 of a step-up transformer 20. Each group of droplets is at first attracted by the next electrode in its path, then (as the excitation voltage changes phase), is propelled by its momentum through the electrode opening, and is then repelled by this electrode and attracted by the next one. Positively-charged groups of droplets emerging from electrode 9 are preferably repelled laterally by a positive electrode 40 and are attracted by a negative electrode 41 to be collected in a container 44, while negativelycharged groups of droplets are similarly collected in a container 46. D.C. output terminals 50 are provided. Nozzle 18 may be connected to rod 15 instead of to earth; the earth centre tap 25 is in that case dispensed with.
