We report on the design, fabrication, and preliminary testing of a 150 zone array built in a `surface-electrode geometry microfabricated on a single substrate. We demonstrate transport of atomic ions between legs of a `Y-type junction and measure the
in-situ heating rates for the ions. The trap design demonstrates use of a basic component design library that can be quickly assembled to form structures optimized for a particular experiment.
This submission is an introduction to microfabricated ion traps. We cover the basics of Paul traps, various geometries for realizing the traps, a number of design considerations, and, finally, a review of existing microfabricated traps.
