Aufbau und Inbetriebnahme einer Raumtemperatur-Elektronenstrahl-Ionenfalle

Electron beam ion traps (EBITs) are capable of producing ions of the highest charge states and are relatively compact and are of lower-cost compared to particle accelerators. Highly charged ions are needed in basic physics research, e.g. for precision measurements in Penning trap mass spectrometers. The present thesis deals with the construction and commissioning of another compact rough-temperature EBIT to produce highly charged ions for the PENTATRAP experiment in the division “Stored and Cooled Ions” at the Max Planck Institute for Nuclear Physics in Heidelberg. So far, the desgin and setup has been succesfully completed within this thesis. Furthermore, the electron gun has been operated at emission currents of over 20 mA and electron beam energies of over 3 keV. The production of ions was successfully tested with argon by observing dielectronic recombinations with a silicon drift detector
