Abstract

Here we present the design, assembly and successful ion trapping of a room-temperature ion trap system with a custom designed and fabricated surface electrode ion trap, which allows for rapid prototyping of novel trap designs such that new chips can be installed and reach UHV in under 2 days. The system has demonstrated success at trapping and maintaining both single ions and cold crystals of ions. We achieve this by fabricating our own custom surface Paul traps in the UMass Amherst cleanroom facilities, which are then argon ion milled, diced, mounted and wire bonded to an interposer which is placed in an ultra-high vacuum chamber and baked in a conventional oven for 46 hours. We demonstrate the system’s ability to confine strontium ions and present preliminary data towards calibrating the ion trap parameters for reduced heating rates. Future work will see the system being used to study the effects of various trap geometries, process fabrication steps and surface treatments on anomalous heating rates, and for portable quantum sensing applications, as an optical atomic clock.
