متن کاملAtomic mass of Li using a Penning-ion-trap mass spectrometer
The atomic mass of Li has been measured using a Penning-ion-trap mass spectrometer to be 6.015 122 795~16! u. The fractional measurement uncertainty of 62.7310 represents a 30-fold improvement over that of the accepted published value. External ion sources were used to create ions outside the cryogenic ~4 K! environment of the Penning trap and an ion-transport beamline was used to deliver ions ...
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 کاملAnd the Penning Trap
This paper begins with some background information and a summary of results in atomic supersymmetry. The connection between the supersymmetric Coulomb and os-cillator problems in arbitrary dimensions is outlined. Next, I treat the issue of finding a description of supersymmetry-based quantum-defect theory in terms of oscillators. A model with an anharmonic term that yields analytical eigenfunct...
متن کاملAn electrostatic autoresonant ion trap mass spectrometer.
A new method for ion extraction from an anharmonic electrostatic trap is introduced. Anharmonicity is a common feature of electrostatic traps which can be used for small scale spatial confinement of ions, and this feature is also necessary for autoresonant ion extraction. With the aid of ion trajectory simulations, novel autoresonant trap mass spectrometers (ART-MSs) have been designed based on...
