    "abstract": "We study the problem of designing electrode structures that allow pairs of\nions to be brought together and separated rapidly in an array of linear Paul\ntraps. We show that it is desirable for the electrode structure to produce a\nd.c. octupole moment with an a.c. radial quadrupole. For the case where\nelectrical breakdown limits the voltages that can be applied, we show that the\noctupole is more demanding than the quadrupole when the characteristic distance\nscale of the structure is larger than 1 to 10 microns (for typical materials).\nWe present a variety of approaches and optimizations of structures consisting\nof one to three layers of electrodes. The three-layer structures allow the\nfastest operation at given distance r from the trap centres to the nearest\nelectrode surface, but when the total thickness w of the structure is\nconstrained, leading to w \u003c r, then two-layer structures may be preferable.",
