This is an important step in the investigation of the suitability of Penning traps for quantum information processing. The magnetron motion was coupled to the laser-cooled modified cyclotron motion by the application of a near-resonant oscillating quadrupole potential (the \"axialization drive\"). Measurement of cooling rates of the radial motions of the ions showed an order-of-magnitude increase in the damping rate of the magnetron motion with the axialization drive applied. The experimental results are in good qualitative agreement with a recent theoretical study. In particular, a classical avoided crossing was observed in the motional frequencies as the axialization drive frequency was swept through the optimum value, proving that axialization is indeed a resonant effect.", "revisions": [ { "version": "v1", "updated": "2007-10-24T08:15:07.000Z" } ], "analyses": { "subjects": [ "03.67.Lx", "37.10.Rs", "41.20.-q" ], "keywords": [ "penning trap", "axialized laser-cooled ions", "magnetron motion", "axialization drive", "near-resonant oscillating quadrupole potential" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2008, "month": "Sep", "volume": 78, "number": 3, "pages": "032307" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvA..78c2307P" } } }
