Abstract
Precision mass measurements are integral in advancing our understanding of nuclear physics. Since mass is a fundamental property of nuclei. TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) facility houses two high-precision mass spectrometers designed for mass measurements of radioactive isotopes: a Multiple-Reflection Time-of-Flight Mass Spectrometer (MR-TOF MS) and a Measurement Penning Trap (MPET).
This thesis presents the results from a MR-TOF MS campaign focused on the measurement of doubly magic 100Sn where we successfully measured isotopes with mass numbers 104 through 107 to a precision of δm/m ≈ 10−7. Additionally, the most precise TITAN trap, MPET, is undergoing a major upgrade aimed at achieving precisions below δm/m ≈ 10−10. As part of this upgrade, a new phase-based measurement technique called Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) is being implemented. To support this implementation, the Phase-Imaging Analysis Tool (PhIAT) was upgraded to assist in system tuning and to perform mass measurements with PI-ICR.
