Method and apparatus for highly sensitive spectroscopy of trapped ions |
摘要 |
An apparatus and method are disclosed for detection of spectra of internal transitions via ion cyclotron resonance techniques. Details of ion containment in a Penning trap and coupling of spin to spatial motions by the addition of a magnetic bottle field are described in both calssical and quantum mechanical formalisms. The invention alters the axial motion of a single ion with a train of spin flips and monitors magnetic resonance through changes in the cyclotron frequency. Detection of such a signal for a single ion (or a small cloud) provides a sensitivity increase of ten to twenty orders of magnitude over conventional magnetic resonance techniques.
