Abstract:
The ALPHATRAP-experiment at the Max-Planck-Institute for Nuclear Physics
is designed to measure the g-factor of the bound electron of heavy highly
charged ions with the help of a Penning trap. The eigenfrequencies are determined
by measuring the induced mirror currents with highly sensitive,
cryogenic amplifiers. To supply the precision electronics and to generate
a stable voltage for the trap-electrodes a precision power supply was built
within this thesis. The priority of this thesis will be the critical points for
development, special features to achieve the stability as well as the layout
and the selection of the used parts. The developed power supply reached a
stability (relative Allan deviation) of 1:8 10-7 in a voltage range of ±10 V
on the timescale of about 15 s to 30 s and exceeds the demanded stability by
about one order of magnitude.
