At TRIUMF’s Ion Trap for Atomic and Nuclear Science (TITAN) the MR-TOF will extend TITAN’s capabilities and facilitate mass measurements and in-trap decay spectroscopy of exotic nuclei that so far have not been possible due to strong isobaric contaminations. The MR-TOF-MS will also enable mass measurements of very short-lived nuclei (T1/2 > 5 ms) that are produced in very low quantities (a few detected ions overall).
In order to allow the installation of an MR-TOF-MS in the restricted space on the TITAN platform, novel mass spectrometric methods have been developed. Ion transport into and out of the device is performed using an RFQ-based switchyard. In addition the exotic ions can be merged with ions from several offline ion sources. Mass selection is performed using a dynamic retrapping technique after time-of-flight analysis. The isobarically clean beam can be provided for the EBIT, Penning trap or in the future to the laser spectroscopy setup.
We report on the commissioning of the system in Giessen and carried out tests and plans for TRIUMF.
