A novel cryogenic Penning trap setup called PENTATRAP is under construction at the Max-Planck-Institut für Kernphysik, Heidelberg. It aims for high-precision mass measurements on highly-charged stable and long-lived single ions related to tests of fundamental symmetries and constants. In order to reach the needed accuracy of 10⁻¹¹ for medium-heavy nuclides a monitoring of the magnetic field in real time in combination with the dip detection technique performed on highly-charged ions will be implemented. The apparatus is planned to be coupled to the EBIT at MPI-K and later to the HITRAP facility at GSI. The design studies of the project will be presented.
