Electron beam ion traps (EBITs) have proven to be versatile and indispensable tools for the production and study of highly-charged ions. In an EBIT, an electron beam is compressed by a strong magnetic field. Usually the field is generated by superconducting magnet coils. To ease operation we introduce a novel magnetic design based on permanent magnets for a 0.74 tesla EBIT. An open trap design offers a large solid angle access to the trap centre. Our EBIT is intended to serve as a reliable source for HCIs. Additionally a new off-axis gun is under construction, to be used at synchrotron and free-electron laser light sources for energy calibration by spectroscopy on HCIs. By using this off-axis gun the photon beam can pass through the EBIT and is available for beamline users. Currently, first experiments with a prototype are carried out regarding trapping an extraction of HCIs.
