Abstract

660,108. Magnetic induction accelerators. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 24, 1947 [Sept. 25, 1946], No. 25950/47. Class 39 (i). In a betatron the rate of change of the magnetic flux is similar to that of the guide field during one part of the operating cycle up to t, and is increased without increasing the rate of change of the guide field during another part of the operating cycle, beyond t, so that as the particles approach high energy levels, undesired deviations of the particles from the equilibrium orbit due to radiation losses are avoided. At time t, a voltage pulse Vc is superimposed of the normal voltage VN for producing the flux #N. The enhanced flux #c compensates for the radiation losses. A second corrective voltage pulse may be applied at a slightly later time. The betatron has a winding surrounding only the central core, and windings surrounding both the orbital path of the particles and the central core. The circuit arrangement is such that the betatron 1:2 relationship is preserved and the voltage pulse applied to the two sets of windings causes the rate of change of the flux to be increased without varying the conditions of the guide field. A D.C. biassing field may be superimposed on the alternating guide field. Specifications 565,864, 574,812, 585,992, and 646,197 are referred to.
