• Mass spectrometry
• Penning trap
• Ramsey excitation

The excitation with time-separated oscillatory fields of the ion's cyclotron motion inside a Penning trap is used to improve the precision of mass measurements. In this work at TRIGA-TRAP the effect of a phase shift of the radio frequency field between the two Ramsey excitation pulses on the resulting ion-cyclotron-resonance time-of-flight line shape is investigated and compared with theoretical predictions.
