要旨:
The Lsym experiment is currently under construction at the Max-Planck-Institute for Nuclear Physics in Heidelberg. The experiment is meant to carry out a precise test of the standard modell. To this end the characteristics of matter and anitmatter will be tested more precisely than ever. This is done by a simultaneous measurement of a helium-ion and a positron within a penning trap. A non-destructive detecting method is used in order to measure the motion of the particles in the trap. This can be achieved by the measurement of mirror currents induced in the trap electrodes by the motion of the ions. The goal of this thesis is the development of one component of the cryogenic detection system for the axial helium frequency. To measure the tiny mirror currents a high quality and low noise detection system is needed. This leads to specific requirements for the detection which this thesis aimes to solve through an optimized high quality resonator being able to be operated at a temperature of 300mK. This thesis aims to optimize the resonator. After the construction the resonator gets thoroughly tested and characterised.
