The Canadian Penning Trap at the N=126 Factory
ORAL
Abstract
The Canadian Penning Trap (CPT) has been located at the CARIBU facility at Argonne National Laboratory's ATLAS accelerator for over a decade, where it has had a spectacularly successful mass spectrometry program, measuring over 200 nuclei produced through the spontaneous fission of 252Cf, recently focusing on masses of interest for the formation of the astrophysical r-process rare earth peak. The CPT will soon be relocating to the new N=126 Factory at ATLAS, where multi-nucleon transfer reactions between two heavy ions will offer a new method of producing heavy, neutron-rich nuclei that cannot be effectively accessed using traditional techniques. The CPT will make use of this facility to study new regions of the chart of the nuclei, like the neutron-rich nuclei near the N=126 shell closure critical for understanding the formation of the r-process A~195 abundance peak, as well as allowing further study of the rare earth peak farther than stability. The status of the N=126 Factory and the proposed measurement program will be presented.
