Abstract: This work was done within the framework of the HITRAP facility, which is designed to decelerate ion bunches down to the sub-eV energy region resulting in a cooled bunch of approximately 105 HCI that can be used for the SPECTRAP experiment, and it was carried out at the GSI/FAIR Institute of Darmstadt in Germany. The SPECtroscopy TRAP, i.e., SPECTRAP, is an experiment located at the ESR hall of this Institute. The main goal of this experiment is to trap highly charged ions, cool them down to ultra-low temperatures and study them with laser spectroscopy. In order for an experiment like this to be performed, a superconducting magnet is needed. In previous years, the magnet suffered damage that caused a liquid helium leakage from the cryostat into the main vacuum, which made storage of HCI next to impossible, and because of that, a new magnet has been procured (a Swedish in-kind contribution to the FAIR facility). There are some major differences between the old and the new magnet; therefore, the need for a new setup arose. The project’s main goal is the design of this new set-up that will operate in the new magnet. The work includes the theoretical calculations for heat influx in the center of the Penning trap located in the center of the experiment. Moreover, simulations have been done to define and optimize the vacuum with the new setup. Furthermore, the design of the new trap was done with the appropriate software, called “Solid Edge”, to build the actual parts of the experiment.
