Abstract

1,087,725. Particle accelerators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 11, 1965 [Nov. 19, 1964], No. 47158/64. Heading H1D. A differential pumping tube arranged in parallel with a D.C. particle accelerator tube and having potential distributing annular electrodes 1 along its length has each electrode comprising a diametral bar 4a, 4b bent out of the plane of the electrode, all the bars being bent towards one end of the tube. An electric field having a component towards the axis of the tube is thereby set up between pairs of adjacent electrodes in order to suppress electron loading. The bars may be bent to V- or arcuate shape and successive bars may be circumferentially displaced through a small angle. Also the inner periphery of each electrode may be bent from the plane of the electrode.
