Abstract
1,142,707. Linear particle accelerators. VARIAN ASSOCIATES. 28 Oct., 1966 [29 Oct., 1965], No. 48525/66. Heading H1D. In a travelling-wave linear accelerator comprising a disc-loaded waveguide, the distance s between input drift tube 31, or the input disc, for the particles and the effective mid-plane of the first cavity D1<SP>1</SP> is set at O#s<L/2 where L is the distance between the midplanes of adjacent cavities. This is to ensure that the injected particles will interact with the maximum strength portion of the acclerating field in the first cavity when there is a large difference between the velocity of the particles and the phase velocity of the travelling wave, e.g. at L-band frequency. In another embodiment the axial length of the first cavity is reduced from the normal length by the distance s. The accelerating waveguide may be designed to have a uniform phase velocity equal to the velocity of light or a phase velocity increasing along the waveguide. An experimental procedure involving the transport of a dielectric bead along the axis of the waveguide is described for determining the phase shift characteristics of the guide.
