Improving the measurement sensitivity of the Canadian Penning Trap mass spectrometer through PI-ICR
For the past two decades the Canadian Penning Trap mass spectrometer (CPT) has been utilized to study various disciplines of nuclear physics through precision mass measurements.

| description | For the past two decades the Canadian Penning Trap mass spectrometer (CPT) has been utilized to study various disciplines of nuclear physics through precision mass measurements. Since moving to the Californium Rare Isotope Breeder Upgrade (CARIBU) facility, the CPT experimental program has focused on neutron-rich nuclei whose masses may play an important role in the astrophysical r process. Through a recent upgrade of the detector system, the phase-imaging ion-cyclotron-resonance (PI-ICR) technique has been successfully implemented. This method offers several benefits which drastically improve the experimental sensitivity of the CPT to the most neutron-rich nuclei produced at CARIBU. Here we describe the PI-ICR procedure at the CPT, give an overview of the systematic sources of uncertainty in the system, and provide new mass results for 142I, 146La, and 163Gd which were made possible through this upgrade. |
