Abstracts:
We study the problem of designing electrode structures that allow pairs
of ions to be brought together and separated rapidly in an array of
linear Paul traps. We show that it is desirable for the electrode
structure to produce a d.c. octupole moment with an a.c. radial
quadrupole. For the case where electrical breakdown limits the voltages
that can be applied, we show that the octupole is more demanding than
the quadrupole when the characteristic distance scale of the structure
is larger than 1 to 10 microns (for typical materials). We present a
variety of approaches and optimizations of structures consisting of one
to three layers of electrodes. The three-layer structures allow the
fastest operation at given distance \rho from the trap centres to the
nearest electrode surface, but when the total thickness w of
the structure is constrained, leading to w
< \rho,
then two-layer structures may be preferable.
