Description
The HIAF project completed technical construction by the end of 2025, and started beam commissioning of the complex thereafter.
In April 2026, high-precision mass measurements of short-lived rare isotopes produced via projectile fragmentation of a $^{209}$Bi beam were successfully conducted with the storage ring SRing and in-flight separator HIRIBL, employing Isochronous Mass Spectrometry, as the first scientific experiment at HIAF.
This mass-measurement campaign aims at neutron-deficient nuclei in the vicinity of $N=82$. Nuclei in this region have long been of great interest because of the robustness of the N=82 shell gap. In this presentation, I will give a general introduction to the experiment, including the experimental setup, preliminary results, and ongoing analysis, as well as future plans for mass measurements of the neutron-deficient nuclei beyond $N=Z$ and the neutron-rich nuclei along $N=126$ at HIAF, which are motivated by the study of the $rp$-process and the $r$-process.
