Study of a electron impact ion source for MR-TOF-MS

The precise mass measurement of exotic nuclei is of special significance to the understanding of the nuclear shell structure and paving the way to shed light on how the heavy elements in universe were made from iron. A Multiple-Reflection Time-Of-Flight Mass Spectrometry has been developed at the Justus Liebig University Giessen in Germany and installed recently at TITAN, to operate as a high-accuracy mass spectrometer and high-resolution isobar separator. To realize high-accuracy mass measurements, calibrants over a broad mass range for calibration and systematic studies of the MR-TOF-MS are essential. The thermal ionization ion sources installed at TITAN can ionize only a limited range of elements now, and it is essential to install a new ion source that can provide a wide mass range of ions for optimization and calibration of the MR-TOF-MS. An electron impact source that satisfies the requirements to ionize a large variety of atoms and small molecules will be studied within this program.
