Phoenix and Peregrine Ion Traps

Abstract

The Phoenix and Peregrine ion traps are micro-fabricated surface-electrode ion traps based on silicon technology. Both are linear traps using a symmetric 6-rail design with segmented inner and outer control electrodes. The traps are fabricated on Sandia's High Optical Access (HOA) platform to provide good optical access skimming the trap surface. They are packaged in custom ceramic pin or land grid array packages using a 2.54 mm pitch. The Peregrine trap is a surface trap with all electrodes in one plane. The Phoenix trap has the same layout, but with a central through-substrate slot and its inner control electrodes are at a lower metal level. Both traps provide means to measure the substrate temperature and to heat the device by means of integrated aluminum and tungsten wires.
