The production of radioactive ion beams via the ISOL method has the advantage of a high yield of the desired radioisotope. The often even higher production and ionization yields of contaminants requires efficient separation methods. The commonly used magnetic separators with mass resolving power of a few 103 allow the separation of contaminants with a mass difference ≥ 1 amu but no preparation of an isobarically clean beam.
TRIUMF’s Ion Trap for Atomic and Nuclear science, TITAN, is a facility for mass measurements, laser spectroscopy and nuclear branching ratio measurements in Vancouver, Canada.
In order to extend TITAN’s capabilities, a specialized multiple-reflection time-of-flight mass spectrometer has been developed in order to provide an efficient, fast (≈ ms), high mass resolving power (≈ 105) and high capacity (> 106 / s) isobar separation of the radioactive nuclei. The separator concept, its design and preliminary results will be presented.
