要旨:
An Electron Beam Ion Trap (EBIT) called table-top EBIT (ttEBIT) was completed and
put into operation within the context of this work. The ttEBIT uses permanent magnets
to produce a peak magnetic field of about 0:7 T. Its small size facilitates its use as a
diagnostic tool in laser spectroscopy as well as its utilisation with free-electron lasers and
synchrotronstrahlung.
A mounting for an electron gun, an electron collector, as well as other components were
designed and installed. Thus the first commissioning of the apparatus and characterisation
of the electron beam was achieved.
Furthermore, a novel off-axis electron gun was developed, which allows for a coaxial
merging of a photon beam and the electron beam. The design was tested using simulation
software and promises good control over the beam characteristics. This was achieved
among other measures by placing sagittal and meridional cuts on the electrodes, which
allows for the steering of the electron beam into the desired direction.
