ABSTRACT
We have characterized ion beams extracted from the Dresden EBIS-A, a compact room-temperature electron beam ion source (EBIS) with a permanent magnet system for electron beam compression, using a pepper-pot emittance meter. The EBIS-A is the precursor to the Dresden EBIS-SC in which the permanent magnets have been replaced by superconducting solenoids for the use of the source in high-ion-current applications such as heavy-ion cancer therapy. Beam emittance and brightness values were calculated from data sets acquired for a variety of source parameters, in leaky as well as pulsed ion extraction mode. With box shaped pulses of C4+ ions at an energy of 39 keV root mean square emittances of 1–4 mm mrad and a brightness of 10 nA mm-2 mrad-2 were achieved. The results meet the expectations for high quality ion beams generated by an electron beam ion source.
