Research in nuclear physics has brought up the request for experiments with high-Z radioactive ions accelerated to the Coulomb barrier and beyond. An efficient way of providing this kinetic energy is charge breeding, i.e. to inject low charged ions into an ion source which converts them into highly charged ions before the actual acceleration takes place. Charge breeding is also interesting for high-precision mass measurements using Penning traps since the accuracy of such experiments is directly proportional to the charge state of the investigated ion.
Electron beam ion traps or sources (EBIT/S) are of great interest for such applications because of their capability of providing beams of high purity and overall quality. Charge breeding with EBITs has been achieved successfully reaching breeding efficiencies of up to 18 %. The purpose of our work is to test the charge breeding performance of Dresden EBIT/S systems using permanent magnets instead of superconducting coils. This results in several advantages such as a compact and transportable design, operation at room temperature and, thus, the economization of resources.
We will present simulations for planned experiments as well as first results and measurements of source characteristics.
