Title: Magnetic induction accelerator
IPC: H05H11/04
Filed: 1950-12-01
Abstract: 693,307. Magnetic induction accelerators. AKT.- GES. BROWN, BOVERI, & CIE. Dec. 1, 1950 [Dec. 2, 1949], No. 29503/50. Class 39(i). in a magnetic induction accelerator with accelerating and guiding fields, one or more pairs of mutually short circuited part circular conductors are arranged symmetrically above and below the equatorial plane of the toroidal discharge tube. The conductors of each pair are connected in opposition so that their induced fluxes normally cancel, but in the event of unequal fluxes existing above and below the equatorial plane the resultant flux is opposed by the induced flux so as to be almost eliminated. In one form, Fig. 1 (not shown) three pairs of conductors of different diameters are provided, the connections between one pair passing outside, and those between the other two pairs passing inside, the wall of the toroid. The toroidal tube preferably has a trapezoidal crosssection. The connections between the pairs may be all inside or all outside the toroid. In another form, Fig. 3, five pairs of partcircular conductors 15, 16 &c. are arranged along one sixth, of the circumference, the conductors of a pair being connected by leads 15a, 15b; 16a, 16b &c. This construction is repeated around the remaining five sixths of the periphery. In another form, Fig. 4, the conductors which may be circular or part circular are formed as copper strips. They are arranged with their widths parallel to the flux lines of the guiding field and tend to improve the homogeneity and direction of the guiding field. Metal strips 19, 20 also assist in achieving these results. In all forms the shorted conductors may be glued or cemented to the tube wall. The output of the discharge device may generate X-rays at an anti-cathode or may produce ionisation in an ionisation chamber.
