Abstract

749,851. Magnetic induction accelerators. BROWN, BOVERI & CO., Ltd. Aug. 19, 1953 [Aug. 19, 1952], No. 22876/53. Class 39 (1). A double beam betatron in which the electrons are alternately accelerated in two opposite directions of rotation, has an orbit expansion coil L surrounding the central flux, connected over two inversely parallel connected thyratrons V1, V2 to a condenser C. The energy of one beam at expansion is regulated by adjusting the phase α1 at which the thyratron V fires, while the energy of the other beam remains constant at approximately its maximum value. The second beam is expanded by firing the thyratron V2 at phase α2= 270‹+#, where # is so chosen that the amplitude of the expansion pulse for the first beam is proportional to the guide flux at the instant of expansion. Acceleration of the first beam commences at phase α=0‹ and of the second beam at phase α=180‹. Fig. 3 shows the voltage UC across the condenser and UL the voltage induced in the expansion coil by the accelerating flux. From this Figure is derived the necessary expression for #. The Specification also describes the derivation of the appropriate voltages applied to the control grids of the thyratrons. Specification 656,627 is referred to.
