Abstract
645,758. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Dec. 11, 1947, No. 32700. Convention date, Dec. 11, 1946. [Class 39 (i)] In a betation, for introducing the electrons into, or abstracting them from, the equilibrium orbit, the radius of the equilibrium circle is changed simultaneously with a displacement of its contre, so that the old and new circles of equilibrium still pass through the same point at one place only in the accelerating tube, thereby preserving the symmetrical distribution of the radial stabilizing forces at that point produced for example by the magnetic guide field for both the old and new circles. As shown in Fig. 6, the anticathode is located at E, and the electron stream is brought from the old circle 10<SP>1</SP> to the new circle of equilibrium 11<SP>1</SP>. At point F the stabilizing forces for the old and new circles are the same. With E representing the location of the electron source, 11<SP>1</SP> is the old and 10<SP>1</SP> the new equilibrium circle. The transition from the old to the new circle is accomplished by an auxiliary coil which is wound to produce oppositely directed fields at points on the orbit situated at opposite ends of a diameter. The radius of the orbit is simultaneously changed by saturating the guide field, or by introducing a phase displacement between the guide field and the induction field.
