Abstract
654,939. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 14, 1947, Nos. 4426, 4427 and 4428. Convention dates, July 14, 1943, Sept. 13, 1943, and Sept. 17, 1943. [Class 39 (i)] In a betatron the electrons are first introduced by means of an auxiliary electrostatic field tangentially into a spiral path, and then into the equilibrium circle. The spiral path is produced by means of a rapidly diminishing radial electrostatic auxiliary field superimposed on the normal magnetic guiding field. As shown, deflector plates P direct the electrons along the path a into the spiral path b. The auxiliary radial field is produced by electrostatic plates P<SP>1</SP>, P<SP>11</SP> concentric with the equilibrium circle K. After acceleration the radial field is rapidly increased so that the radius of the equilibrium circle increases until the electrons come under the influence of the ejector plates A. The ejector plates may form continuations 2 of, but electrically insulated from, the plates P<SP>1</SP>, P<SP>11</SP>. The plates Z extend preferably over <SP>1</SP>/ 5 th to <SP>1</SP>/ 10 th of the equilibrium circle, and are most favourably located at a point where the transverse oscillation of electrons about the equilibrium circle in the stabilizing field of force, is a maximum. This point is at a quarter-wavelength of the transverse oscillation from the point of ejection. On ejection the electrons may be led to an anticathode, or to an ionization chamber I. The radial auxiliary field may increase in intensity inwardly or outwardly to provide an axial stabilizing force component.
