Highly charged ions for mass determinations of short-lived isotopes — •Martin C. Simon1, Dieter Frekers2, Vanessa V. Simon1,3,4, José R.

TRIUMF*s Ion Trap for Atomic and Nuclear science (TITAN) is the only high precision Penning trap mass measurement setup coupled to a rare isotope facility using charge breeding of short-lived nuclides for accurate mass determinations [1,2].
Experiments on isotopes with half-lives as low as 65 ms, such as 74-Rb [3], and in charge states as high as 22+ have been carried out. Results on Ge and Ga relevant to neutrino-detector flux calibrations will be reported. Future plans include a new electron beam ion source for re-acceleration applications [4].
