Description
The Canadian Penning trap (CPT) is currently located at Argonne National Laboratory in the CARIBU facility where intense beams of neutron-rich nuclei are produced from the spontaneous fission of $^{252}$Cf. The focus of the current CPT campaign is to provide precision mass measurements of nuclides involved in the astrophysical r-process. To date more than 110 nuclides have been measured to an average mass precision of $\delta m/m \approx 10^{-7}$ using the time-of-flight ion-cyclotron-resonance method. At CARIBU this technique only allows the CPT to probe nuclides with half-lifes longer than $\sim 200$ms and fission branches larger than $5\times10^{-4}$%. An upgrade of the CPT detector system to a phase-imaging technique is currently underway which will shorten measurement cycles by a factor of 5-10, allowing us to probe nuclei 1-3 neutrons further from stability than is currently possible.
