Join us for this PSI seminar with guest speaker Dr Lukas Nies. Measuring atomic masses allows us to draw conclusions on the structure and properties of the atomic nucleus, and thus, mass spectrometry has played a big role in nuclear physics studies. Over many decades, various mass measurement techniques have been employed to extract masses from singly charged or highly charged ions, many utilizing strong magnetic fields. Fast techniques, which can perform high-resolution (m/?m > 100,000) mass spectrometry in a very short amount of time (< 100ms), are especially important when studying short-lived radioactive isotopes. In this contribution, we will explore the use of Multi-Reflection Time-of-Flight Mass Spectrometers (MR-ToF MS) at the radioactive ion beam facility ISOLDE at CERN, Switzerland. At ISOLDE, several different MR-ToF MS are employed for mass spectrometry, mass separation, and species identification. Conventional devices used at similar facilities are operated at standard ion beam energies of one to two kiloelectronvolt, whereas in ISOLDE’s new development device, ion beam energies of up to ten to twenty kiloelectronvolts are possible, promising faster and more precise measurements.
