Atomic masses represent key ingredients to understand the structure of atomic nuclei. In particular, they provide insights into the nuclear binding energy and, thus, into the combined forces that govern the stability of atomic nuclei. Given their high experimental precision and accuracy, these observables serve as stringent benchmarks for modern nuclear theory and are critical input for nuclear astrophysics and tests of fundamental symmetries. Here, we review the current status of precision atomic mass measurements, with a focus on short-lived radioactive species and relevant techniques employed at TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN). Coupled to the ISAC facility, TITAN has been in operation since 2007. Over the years, it has evolved in its capabilities, taking advantage of its unique combination of ion traps, including Paul traps, an electron beam ion trap (EBIT), a Penning trap, and most recently, an electrostatic multiple-reflection time-of-flight (MR-TOF) system.
