In order to study the effect carbon contamination has on surface noise while avoiding additional effects cleaning may have on the surface, our current experiment uses electron-beam-induced deposition using an ethylene precursor gas to deposit several monolayers of carbon onto the surface of an ion trap. Initial measurements of the noise before and after deposition suggests an order-of-magnitude increase in noise due to the carbon contamination. A second deposition experiment with a new trap is underway to confirm these results.
