Isotopes at the limits of nuclear existence are great interest for their critical role in astrophysical reactions and exotic structure. Experimentally, nuclides challenging to address due low production cross-sections, overwhelming amounts contamination, lifetimes typically less than a second. To this end, Multiple-Reflection Time-of-Flight mass spectrometer TITAN-TRIUMF facility was built determine atomic masses. This device is preferred tool work with its ability resolve species from...
High-accuracy mass measurements of neutron-deficient Yb isotopes have been performed at TRIUMF using TITAN's multiple-reflection time-of-flight spectrometer (MR-TOF-MS). For the first time, an MR-TOF-MS was used on line simultaneously as isobar separator and a spectrometer, extending to two further away from stability than otherwise possible. The ground state masses $^{150,153}\mathrm{Yb}$ excitation energy $^{151}{\mathrm{Yb}}^{m}$ were measured for time. As result, persistence $N=82$ shell...

Direct observation of proton emission with very small energy is often unfeasible due to the long partial half-lives associated tunneling through Coulomb barrier. Therefore emitters Q-values may require masses both parent and daughter nuclei establish them as unbound. Nuclear mass models have been used predict drip-line thulium (Tm) isotopic chain ($Z=69$), but up until now separation has not experimentally tested. Mass measurements were therefore performed using a Multiple Reflection...
Line coincidence photopumping is a process where the electrons of an atomic or molecular species are radiatively excited through absorption line emission from another at coincident wavelength. There many instances in astrophysical sources optical and ultraviolet wavelengths, with most famous example being Bowen fluorescence (pumping O III 303.80 A by He II), but none to our knowledge X-rays. However, here we report on scheme He-like Ne IX 11.000 photopumped Na X 11.003 A, which predicts...
The controlled focusing and transport of ion beams is paramount importance in particle accelerators, high energy beamlines, detector systems, as it determines the sensitivity resolution instruments. Therefore, essential to model beam dynamics before commissioning new instruments order optimise properties such transmission spread. In this paper, a commercial Plasma Ion Source (PIS), comprised heated filament anode followed by its collimating optics, was modelled using Monte Carlo simulations...
