偶极和单相双电极四极检测方案进行了研究，在傅里叶变换离子回旋共振质谱（FT-ICR MS）的KATRIN实验在马克斯-普朗克核物理研究所（MPIK）在海德堡的设置。我们目前的第一个实验结果7 Li+信号从一个圆柱形的潘宁陷阱配置两个检测方案。虽然常规偶极检测方案的突出信号标记降低的回旋频率，但是四极检测的主信号出现在降低的回旋频率和磁控管频率的和处。对于理想的俘获场，该和频率等于离子回旋频率νc = qB/（2πm）。由于回旋模式和磁控管模式的组合运动的边带被观察到由四极检测，其允许本征频率的相应组合的确定。
Dipolar and single-phase two-electrode quadrupolar detection schemes have been investigated at a Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) setup built for the KATRIN experiment at the Max-Planck-Institute for Nuclear Physics (MPIK) in Heidelberg. We present first experimental results of 7Li + signals from a cylindrical Penning trap configuration for both detection schemes. While the prominent signal of the conventional dipolar detection scheme marks the reduced cyclotron frequency, the main signal for the quadrupolar detection appears at the sum of the reduced cyclotron frequency and the magnetron frequency. For ideal trapping fields, this sum frequency equals the ion cyclotron frequency νc = qB/(2πm). Sidebands due to the combined motions of the cyclotron mode and magnetron mode are observed by quadrupolar detection which allows the determination of the respective combinations of eigenfrequencies.
