要旨:
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.
