Mass Measurements for the r-Process using the Canadian Penning Trap

The masses of neutron-rich isotopes are essential to abundance calculations for nuclei produced by the rapid neutron capture process (r-process) during neutron star merger events and other possible astrophysical phenomena. The abundance pattern of nuclei produced by this process shows peaks surrounding neutron shell closures and a smaller peak in the rare-earth region with strong sensitivity to astrophysical conditions. Isotopes in the region of interest for the heaviest r-process peak have been hard to produce, but Argonne National Laboratory's N=126 Factory will utilize multi-nucleon transfer reactions in order to access them. The Canadian Penning Trap (CPT) mass spectrometer is being relocated to embark on a high-precision mass measurement campaign of these nuclides. The commissioning of the N=126 Factory and the planned measurement campaign will be presented.
