Division of Nuclear Physics Stuart Jay Freedman Award: Precision mass measurements for nuclear physics*

Ion traps have long been used in atomic physics to achieve high precision and accuracy. They have since been deployed at radioactive-ion-beam facilities, primarily for Penning trap mass spectrometry. This has been exemplified by TRIUMF’s Ion Trap for Atomic and Nuclear science, TITAN. The combination of four on-line ion traps allows for sophisticated manipulation of a single ion or a cloud for beam preparation and measurements. Precision mass measurements have been used to map the island of inversion at N=20, to observe the emergence of the N=32 subshell, to study nucleosynthesis in neutron-rich nuclei, and to test the unitarity of the quark-mixing matrix. I will interleave scientific highlights with the technical developments leading to them.
