Nuclear physics experiments probe nuclear structure, nucleosynthesis, and fundamental interactions, for which high precision and accurate mass measurements are critical inputs. TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) facility employs the Measurement Penning Trap (MPET) to measure masses of exotic nuclei to high precision and accuracy with a goal of dm/m up to ~10-10. To improve the resolving power and to reduce the statistical uncertainty in the mass measurement, a higher charge state of the ions can be used. This and other benefits of charge breeding radionuclides like improved beam purification can be realized only at TITAN as it alone combines radioactive ions, charge breeding, and a Penning trap. To fully leverage these advantages, MPET underwent an upgrade to a new cryogenic vacuum system compatible with ions in charge states over 20+. The status of cryogenic Penning trap will be presented, along with the preliminary results from the first radioactive ion beam experiment done with the upgraded trap.
