The ion-optical design of a multiple reflection time-of-flight mass spectrometer and isobar separator (MR-TOF-MS) is presented. The MR-TOF-MS has been developed for the research with exotic nuclides at accelerator facilities and has been designed to provide a mass resolving power (FWHM) exceeding 300,000 and a mass accuracy of down to 10 −7 . High-performance axially symmetric four-electrode gridless ion mirrors have been developed and optimized for the device. In addition, the MR-TOF-MS comprises several further novel ion-optical elements such as an isochronous post-analyzer reflector and an energy bunching and deceleration system for ion injection into an accumulation trap. The device has been built and commissioned and shows superb performance characteristics in accordance with the design criteria. [ABSTRACT FROM AUTHOR]
