Abstract

903,962. Linear particle accelerators. HIGH VOLTAGE ENGINEERING CORPORATION. July 6, 1959, No. 23094/59. Class 39 (1). A microwave linear accelerator consists of a loaded accelerator and buncher waveguide section 2, fed by a power source 10 such as a magnetron, into which electrons are injected at less than the velocity of light, and utilizes negative feed-back via arm 7 from the beam emergent end of waveguide 2 to produce feedback energy, out of phase with the input power from source 10, at the input end of guide 2. The buncher waveguide is followed by a main accelerator waveguide 3 which the bunched beam enters at approximately the velocity of light. The phase velocity along waveguide 2 increases with the beam velocity. Phase shifter 11 shifts the phase of the feed-back by #, or phase shifter 11 may be dispensed with by suitably designing the waveguide bridge 4 into an annular rat-race waveguide or a magic T having a circumference of <SP>3</SP>/ 2 #, 6, 7, 8 being # 4 , # 2 , # 4 , from 5 so power from 10, 5 goes into 6, 8 but not into 7. The cross-section of the rat-race is varied to adjust the power it delivers to buncher waveguide 2. Power is fed via arm 6 and phase shifter 12 to the main accelerating waveguide 3.
