Ramsey method of separated oscillatory fields for high-precision penning trap mass spectrometry.
Ramsey's method of separated oscillatory fields is applied to the excitation of the cyclotron motion of short-lived ions in a Penning trap to improve the precision of their measured mass values. The theoretical description of the extracted ion-cyclotron-resonance line shape is derived and its correctness demonstrated experimentally by measuring the mass of the short-lived 38Ca nuclide with an u...
متن کاملPosition-sensitive ion detection in precision Penning trap mass spectrometry
A commercial, position-sensitive ion detector was used for the rst time for the time-ofight ion-cyclotron resonance detection technique in Penning trap mass spectrometry. In this work, the characteristics of the detector and its implementation in a Penning trap mass spectrometer will be presented. In addition, simulations and experimental studies concerning the observation of ions ejected from ...

متن کاملEUROPEAN ORGANISATION FOR NUCLEAR RESEARCH Ramsey Technique Applied in a Penning Trap Mass Spectrometer
The Ramsey method has been applied in an experiment aiming for accurate mass determination of unstable isotopes. The ion motion in a Penning trap has been excited with time-separated oscillatory elds and Ramsey fringes were observed in the case of dipole and quadrupole excitation. The experimental resonances are in good agreement with theory. Further applications of the technique are discussed....
متن کاملPreparing isomerically pure beams of short-lived nuclei at JYFLTRAP
A new procedure to prepare isomerically clean samples of ions with a mass resolving power of more than 1×10 has been developed at the JYFLTRAP tandem Penning trap system. The method utilises a dipolar rf-excitation of the ion motion with separated oscillatory fields in the precision trap. During a subsequent retransfer to the purification trap, the contaminants are rejected and as a consequence...
