Cooling of heavy highly charged ions: The HITRAP-Penning Trap — •Dimitrios Zisis for the Hitrap collaboration — GSI Helmholtzzentrum für Schwerionenforschung, Germany — Technical University of Darmstadt, Germany

For conducting high-precision experiments at low energies and small energy distributions, heavy and highly charged ions (HCI) need to be decelerated and cooled, which is the aim of the HITRAP facility. It is situated at the GSI Helmholtzzentrum für Schwerionenforschung, where a wide range of HCI can be provided. Its unique capability to decelerate and cool HCI, not only enables easier ion storage and manipulation but also further transport towards attached experiments.

At HITRAP, HCI are decelerated in a two-step process from 4 MeV/u to 6 keV/u before being captured in a Penning trap for electron cooling. This cooling process precedes the subsequent ejection of ions, facilitating their transport to various precision experiments.

We present the latest successful outcomes in electron cooling of HCI. Despite the observed reduction in ion energy, a detailed investigation of systematic effects has yet to be carried out. Future steps involve the optimization of the cooling process including more advanced detection methods and further systematic studies.
